Answer:

v₃ = 4.33 [m/s]

Explanation:

This problem can be solved by the conservation of linear momentum, where momentum is preserved before and after the crash or collision.

For this case, the following equation will be constructed. With values before the collision to the left of the equal sign and after the collision to the right of the equal sign.

[tex](m_{1}*v_{1})+(m_{2}*v_{2})=(m_{1}+m_{2})*v_{3}[/tex]

where:

m₁ = mass of the big football player = 130 [kg]

m₂ = mass of the second football player = 110 [kg]

v₁ = velocity of the big football player before the collision = 8 [m/s]

v₂ = velocity of the second football player before the collision = 0 (who is standing still).

v₃ = velocity of the two players after the collision [m/s]

Now replacing:

[tex](130*8)+(110*0)=(130+110)*v_{3}\\1040 = 240*v_{3}\\v_{3}=4.33[m/s][/tex]

Answer:

The amount of potential energy stored in the magnetic field depends on both the strength of the magnet and the distance that another magnet or magnetic object is from it. ... All objects have a gravitational force, no matter how small, but only some objects such as iron objects can have a magnetic force.

Explanation:

The potential energy stored in the magnet/iron rod system is on the account of distance of each entities and the strength of magnets.

The given problem is based on the concept of potential energy stored in magnetic rod system.

Thus, we can conclude that the potential energy stored in the magnet/iron rod system is on the account of distance of each entities and the strength of magnets.

Answer:

1800J

Explanation:

Given parameters:

Weight of the book  = 20N

Total distance covered  = 45m + 15m + 30m  = 90m

Unknown:

Total work performed on the books  = ?

Solution:

To solve this problem we must understand that work done is the force applied to move a body through a certain distance.

So;

    Work done  = Force x distance

  Work done  = 20 x 90  = 1800J

Answer:

Na⁺

Explanation:

In the given atom:

  Number of protons  = 11

  Number of neutrons  = 12

So, the number of electrons  = 10

The number of protons within an atom is used to determine the kind of atom we have been given.

Since the number of protons is the same as the atomic number, here the atomic number is 11 and this is Sodium .

 In this sodium atom, the number of protons is more than the number of electrons;

 Charge = number of protons  - number of electrons  = 11 - 10  = +1

So, we have a Na⁺

Answer:

6.07 N

Explanation:

Given that,

Force, F = 35 N

It makes 10 degree angle with the positive x-axis.

We need to find the magnitude of the vertical component of the force. It can be given by :

[tex]F_y=F\sin\theta\\\\=35\times \sin(10)\\\\=6.07\ N[/tex]

So, the magnitude of the vertical component of the force is 6.07 N.

Answer:

Vertical component of force is equal to [tex]6.067[/tex] N

Explanation:

The magnitude of the vertical component on any force when α is the angle between the direction of force and the X -axis is

[tex]F_y = F * Sin\alpha[/tex]

Substituting the given values in above equation, we get -

[tex]F_y = 35 * Sin 10\\F_Y = 35 * 0.1736\\F_Y = 6.067[/tex]

Vertical component of force is equal to [tex]6.067[/tex] N

The mass of the basswood wing with the given dimension is 710.14 g.  Basswood is a low-density, light wood.

Basswood is a low-density, light wood that is mainly used for artistic work such as hand carving and creating musical instruments.

The mass can be calculated by the formula,

[tex]m = v \times d[/tex]

Where,

[tex]m[/tex]- mass

[tex]v[/tex] - volume = 26.9 cm x 5.5 cm x 0.15 cm =  22.192 ml

[tex]d[/tex] - density = 32 g/cm3

Put the values in the formula,

[tex]m[/tex] = 22.192  x 32

[tex]m[/tex] = 710.14 g

Therefore, the mass of the basswood wing with the given dimension is 710.14 g.

Answer:

The horizontal speed with which the slingshot hits the balloon is approximately 57.358 m/s

Explanation:

The given parameters of the slingshot motion are;

The initial velocity of the slingshot, v = 100 m/s

The angle (to the horizontal) at which the slingshot is fired makes, θ = 55°

The path of the slingshot which hits the stationary balloon at the top of its flight = Parabolic trajectory

The horizontal component of the velocity = vₓ = v·cos(θ) = Constant

vₓ = 100 × cos(55°) ≈ 57.358

The horizontal speed with which the slingshot hits the balloon = vₓ ≈ 57.358 m/s.

Explanation:

Starting position at x  = 16m

Ending position at x  = -25m

Time of flight  = 4s

Unknown:

Distance flown  = ?

Displacement  = ?

Speed  = ?

Velocity  = ?

Solution:

To find the distance flown, we should understand that the body is moving on the x - plane;  

  So distance  = 16 + 25  = 41m

Displacement is 41m to the left or -x axis

Speed is the distance divided by the time taken;

      Speed  = [tex]\frac{distance}{time}[/tex]   = [tex]\frac{41}{4}[/tex]   = 10.25m/s

Velocity is 10.25m/s along -x axis
