Consider a system to be two train cars traveling toward each other.

What is the total momentum of the system before the train cars collide? (1)

What must the total momentum of the system be after the train cars collide? (2)

1) 1,600 kg • m/s 2) 1,600 kg • m/s

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?

2,400 kg • m/s

Two billiard balls move toward each other on a table. The mass of the number three ball, m1, is 5 g with a velocity of 3 m/s. The mass of the eight ball, m2, is 6 g with a velocity of 1 m/s. After the balls collide, they bounce off each other. The number three ball moves off with a velocity of 5 m/s. What is the final velocity and direction of the eight ball?

+5.7 m/s

Two balls, each with a mass of 0.5 kg, collide on a pool table. Is the law of conservation of momentum satisfied in this collision? Explain why or why not

Yes, the law of conservation of momentum is satisfied. The total momentum before the collision is 1.5 kg • m/s, and the total momentum after the collision is1.5 kg • m/s. The momentum stays the same after the collision.

Train car A is at rest when it is hit by train car B. The two cars, which have the same mass, stick together and move off after the collision. How does the final velocity of train cars A and B after the collision compare to the initial velocity of train car B before the collision?

The final velocity is half of train car B's initial velocity.

During a game of marbles, a player is trying to win a 2 g marble that is at rest. The player flicks a 1.25 g marble at a velocity of 8 m/s at the larger marble that is sitting still. After the collision, the smaller marble has a velocity of 1 m/s

What is the velocity of the 2 g marble after the collision? Round your answer to the nearest whole number.

4 m/s

A cue ball has a mass of 0.5 kg. During a game of pool, the cue ball is struck and now has a velocity of 3 m/s. When it strikes a solid ball with a mass of 0.5 kg, the cue ball comes to a complete stop. What is the new velocity of the solid ball? Round your answer to the nearest whole number.

3 m/s

Suggest the variation in the output voltage from the light sensor that will be observed as the train moves beyond the first diffraction minimum.

True or False: The acceleration of an object is directly dependent upon its mass and inversely dependent upon its net force.

If no force is applied to a moving object, it will continue to move with constant speed in a straight line.

A force of 10 N acts on a charge of 5.0 ìC when it is placed in a uniform electric field. What is the magnitude of this electric field?

Two balls, each with a mass of 0.5 kg, collide on a pool table. is the law of conservation of momentum satisfied in this collision? explain why or why not. Answers

The answer is going to be c there is no change in the electric potential energy as it is in rest on both conditions.

Yes, the law of conservation of momentum is satisfied. The total momentum before the collision is 1.5 kg • m/s and the total momentum after the collision is 1.5 kg • m/s. The momentum before and after the collision is the same.

Thanks Useless
