The acceleration of the object is 4 m/s².

We know that, the relationship between velocity and acceleration

Acceleration (a) = Rate of change in velocity

or a = dv/dt

so, acceleration = slope of a velocity vs. time graph

a = [tex]\frac{v2-v1}{t2-t1}[/tex]

when t=0, v = 0 and when t = 5sec, v = 20 m/s

It is more difficult to start a train moving due its larger mass that will produce a smaller acceleration compared to an average sized car for an equal applied force.

Also is more difficult to bring a train to a stop than an average sized car, because the train exerts a larger force than the average sized car.

Newton's first law of motion states that an object at rest or uniform motion in a straight line will continue in that path unless an external force acts on the object and the object will move in the direction of the applied force.

Newton's first law of motion is known as inertia because, it depends on the mass of the object.

According to Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.

Mathematically, the formula for Newton's second law of motion is given as;

F = ma

where;

The acceleration of an object is determined from Newton's second law of motion;

a = F / m

Thus, from the equation above, the greater the mass of an object, the smaller the acceleration of the object for a constant force.

Also an object with a large mass such as a train will require large force of friction to be brought to rest since the force exerted by the train will be great due to its large mass.

Explanation:

Because of the law of conservation of momentum (total momentum of two golf balls must be constant).

In the circular motion, the system is open, because a net force is exerted on the ball as it travels in a circle. Option B

We know that the term circular motion would have to do with the kind of motion that is occurring in a circular path. We have to know that the velocity of the object may be constant but the object may still be said to be accelerating.

Given the fact that we know that the acceleration of the ball is not the same at all the points of the circle as we can see it then it follows that the system is an open system as the net force acts on it.

On a speed-time graph, the line representing the motion of the car would be a straight line with a positive slope. This is because the speed of the car is increasing, so the line on the graph would slope upwards from left to right.

On a distance-time graph, the line representing the motion of the car would also be a straight line, but with a slope that is greater than that of the line on the speed-time graph.

This is because distance is the product of speed and time, so if the speed of the car is increasing, the distance traveled by the car will also be increasing at an increasing rate. The line on the distance-time graph will therefore have a steeper slope than the line on the speed-time graph.

If more resistors are added in series to a battery with zero internal resistance, the power supplied by the source decreases.

The reason is that adding more resistors will increase the total resistance and decrease the current through all resistors. The new total resistance is: Rtot = R₁ + R₂ + R₃ + ...

And we know from ohm's law, V/I = R.

From here, we can see that when we add more resistors in series, we have more voltage across each individual part of our circuit, but less current flowing through each part of it. That means our total power supplied by the source decreases because there is less current flowing through the resistors when combined.

Magnetic Field:

A magnetic field is the vector field that depicts how the magnetic force is distributed within or around a certain magnetic substance. The magnetic field, which consists of closed loops, travels from the North Pole to the South Pole.

Given Data:

The charge on the proton is:

q = 1.6 × 10⁻¹⁹ C

The mass of the proton is:

m = 1.67 × 10⁻²⁷ Kg

The distance by which the magnetic field extends is:

D = 0.44 m

The velocity of proton in x direction is:

vₓ = 5.1 × 10⁵ m/s

The velocity of proton in y direction is:

v = 2.7 × 10⁵ m/s

Answer and Explanation:

(1):The expression for the resultant velocity when the proton enter the magnetic field is,

[tex]v = \sqrt{v_{x^2} +v_{y^2}}[/tex]

Substitute the values in above expression.

[tex]v = \sqrt({5.1 * 10^{5} m/s} )^{2} + ({2.7 * 10^{5} m/s} )^{2}[/tex]

[tex]v = 5.8 * 10^{5} m/s[/tex]

Thus, the resultant velocity when the proton enter the magnetic field is [tex]v = 5.8 * 10^{5} m/s[/tex]

(2): The expression for the angle of inclination of proton is,

tanΘ =  [tex]\frac{v_{x} }{v_{y} }[/tex]

Substitute the values in above expression.

tanΘ =  [tex]\frac{2.7 * 10^{5 }m/s }{5.1 * 10^{5} m/s}[/tex]

= tan⁻¹(0.53)

Θ= 27.92°

The expression for the radius of curvature is,

[tex]R = \frac{D}{sin \theta}[/tex]

Substitute the values in above expression.

R= [tex]\frac{0.44 m}{sin 27.92}[/tex]

R≈ 0.94 m

Thus the radius of curvature is 0.94 m

(3): The expression for the y coordinate of proton is,

[tex]h = R -\frac{D}{tan \theta}[/tex]

Substitute the values in above expression.

[tex]h = 0.94 m -\frac{0.44 m}{tan \ 27.92}[/tex]

[tex]h=0.11 m[/tex]

Thus, the y coordinate of proton is 0.11 m

(4): The expression for the z component of the magnetic field is,

[tex]B_{z} =\frac{m*v}{q*R}[/tex]

Substitute the values in above expression.

[tex]B_{z} =\frac{(1.6 * 10^{-27 }kg) *(5.8*10^{5}m/s ) }{1.6*10^{-19} *0.94 m}[/tex]

[tex]B_{z} =6.44 * 10^{-3} kg/C.s[/tex]

Thus, the z component of the magnetic field is [tex]6.44 * 10^{-3} Kg/C.s[/tex]

(5): The radius of curvature would rise by the same amount if the velocity were increased because R varies linearly with v. The angle of incidence also lowers as the radius of curvature increases. The displacement h likewise decreases as the angle narrows.

Answer:

a.) 12[tex]\frac{rad}{s^2}[/tex]

b.) 48[tex]\frac{rad}{s}[/tex]

c.) 23.87 rev

Explanation:

First, convert linear velocity to angular velocity.  The angular velocity can be calculated using the relationship v=rω, where v is the linear velocity, r is the radius, and ω is the angular velocity.  Rearrange the equation to solve for ω:

[tex]\omega=\frac{v}{r}[/tex]

For this problem, let v=30[tex]\frac{m}{s}[/tex] and r=0.5m.  So,

[tex]\omega=\frac{30\frac{m}{s}}{0.5m}\\\omega=60\frac{rad}{s}[/tex]

Next, to solve for angular acceleration use rotational motion equation #1, [tex]\omega_f=\omega_i+\alpha t[/tex].  For this problem, let

[tex]\omega_i=0.0\frac{rad}{s}\\\omega_f=60\frac{rad}{s}\\t=5s[/tex]

So,

[tex]60\frac{rad}{s}=0.0\frac{rad}{s}+\alpha(5s)\\(\frac{1}{5s})60\frac{rad}{s}=\alpha(5s)(\frac{1}{5s})\\12\frac{rad}{s^2}=\alpha[/tex]

Next, use the angular acceleration and the time given in part b in rotational motion equation #1 to solve for the angular velocity at t=4s:

[tex]\omega_f=\omega_i+\alpha t\\\omega_f=0.0\frac{rad}{s}+(12\frac{rad}{s^2})(4s)\\\omega_f=48\frac{rad}{s}[/tex]

To find the number of revolutions, use rotational motion equation #3, [tex]\theta=v_it+\frac{1}{2}\alpha t^2[/tex], to find the angular displacement at t=5s.  So,

[tex]\theta=0.0\frac{m}{s}(5s)+\frac{1}{2}(12.0\frac{rad}{s^2})(5s)^2\\\theta=0.0m+150\ rad\\\theta=150\ rad[/tex]

To convert the angular displacement in radians to revolutions, recall that one revolution equals 2π radians.  So,

[tex]150\ rad(\frac{1\ rev}{2\pi\ rad})=\frac{75}{\pi}\ rev\approx23.87\ rev[/tex]
