Consider a system to be one train car moving toward another train car at rest. When the train cars collide, the two cars stick together. What is the total momentum of the system after the collision? 800 kg • m/s 1,600 kg • m/s 2,400 kg • m/s 4,000 kg • m/s.
The momentum of the body is given by the product of the mass and velocity of the body. The total momentum of the system after the collision is 2400 kgm/sec.
What is the law of conservation of momentum?According to the law of conservation of momentum, the momentum of the body before the collision is always equal to the momentum of the body after the collision.
The momentum of the body is given by the product of the mass and velocity of the body.
According to the law of conservation of momentum
Momentum before collision =Momentum after collision
The given data in the problem is;
mass of train m₁ = 600
mass of car m₂= 400
the velocity of train = 4 m/sec
velocity of car =0 m/sec (rest)
Momentum after collision;
[tex]\rm M_f=m_1v_1+m_2v_2 \\\\\ \rm M_f=600 \times 4 +400 \times 0 \\\\ \rm M_f=2400\;kgm/sec[/tex]

9. Why does water behave in this unusual fashion?
Answer:
Why does water behave in this unusual fashion? The atmospheric pressure decreases as the elevation increases. This affects the boiling point because at a higher elevation, when there is less atmospheric pressure, there is less energy holding the water particles in place.

You push horizontally on a 120-N box that is initially resting on a horizontal table. The coefficient of static friction between the box and the table is 0.75, and the coefficient of kinetic friction is 0.40. Find the friction force on the box if the push is equal to(a) 84 N; (b) 94 N.
(a) When the applied force is 84 N, the friction force on the box is 36.02 N.
(b) When the applied force is 94 N, the friction force on the box is 46.02 N.
Frictional force on the boxThe frictional force on the box when it is pushed with a certain force is calculated as follows;
Ff = μFₙ
F - Ff = ma
Mass of the box is calculated as follows;
W = mg
m = W/g
m = 120/9.8
m = 12.24 kg
Acceleration of the box is calculated as follows;
a = μg
a = 0.4(9.8)
a = 3.92 m/s²
When the applied force is 84 N,
F - Ff = ma
F - ma = Ff
84 - 12.24(3.92) = Ff
36.02 N = Ff
When the applied force is 94 N,
F - Ff = ma
F - ma = Ff
94 - 12.24(3.92) = Ff
46.02 N = Ff

A 200 kg man is stuck, motionless, in the middle of a frictionless ice pond. Because it's cold, he's wearing a coat. He wants to get off the pond. Since he has studied physics and knows about conservation of momentum, he decides to throw his 4 kg coat. If he throws the coat at 50 m/s, what will his speed be
The speed of the man when he throws the coat is 1 m/s.
Conversion of linear momentumThe speed of the man can be determined by applying the principle of conservation of linear momentum as follows;
m₁v₁ = m₂v₂
v₁ = (m₂v₂)/m₁
v₁ = (50 x 4)/200
v₁ = 1 m/s
Thus, the speed of the man when he throws the coat is 1 m/s.

The velocity of the roller coaster at the top of the second hill is 24.25 m/s.
What is velocity?
Velocity is the rate of change of displacement. The s.i unit is m/s
To calculate the velocity of the coaster car, we use the formula below.
Formula:
mg(H-h) = mv²/2............... Equation 1Where:
m = mass of the coaster carH = Height of droph = Height of the second hillv = velocity of the roller coaster.From the question,
Given:
m = 750 kgH = 90 mh = 60 mg = constant = 9.8 m/s²Substitute these values into equation 1
750(9.8)(90-60) = 750(v²)/2Solve for v
375v² = 220500v² = 220500/375v² = 588v = √588v = 24.25 m/sHence, The velocity of the roller coaster at the top of the second hill is 24.25 m/s.

Newton second law of motion is F =ma
Answer: ma is the formula of Newton's Second Law of Motion. Newton's Second Law of Motion is defined as Force is equal to the rate of change of momentum. For a constant mass, force equals mass times acceleration.
Explanation: Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
Hi there!
Using Newton's Second Law:
[tex]F = ma[/tex]
F = Net Force (60 N)
m = mass (30 kg)
a = acceleration (m/s²)
Solve for acceleration given the other values.
[tex]60 = 30a\\\\a = \frac{60}{30} = \boxed{2 \frac{m}{s^2}}[/tex]
If the net force increases (while the mass is held constant), the acceleration will INCREASE.
If the mass of the object increases (while the net force is held constant), then the acceleration will DECREASE.

1. How fast is each cyclist going in units of meters per second*?
2. Which cyclist is going faster? How much faster is this cyclist going compared to the other one?
Answer:
1. a = 1m/s
b = 3m/s
2. b is faster by 2m/s
Explanation:
v (speed) = d/t
va (speed for cyclist a) = 5/5

Electrical energy is supplied to a string of lights. What forms of energy are lost?
Answer:
In what forms is the electrical energy that is supplied to a string of decorative lights dissipated? It is converted to thermal energy and light energy.
Answer:
Energy loss. When energy is transformed from one form to another, or moved from one place to another, or from one system to another there is some energy loss. This means that when energy is converted to a different form, some of the input energy is turned into a highly disordered form of energy, like heat.
Energy losses in lights are very large; most of the input energy is lost in the form of heat energy.
