1. Two Train cars of identical mass (m = 10.0 kg) collide

and move off as shown. The left car was initially traveling at 2.0 m/s right and the right car was initially traveling at a velocity of 3.0 m/s left. After the collision, the left car is traveling at a velocity of 2.5 m/s to the left.

a. What type of a collision is depicted here?

000000

b. What was the initial momentum of the right car?

c. What was the initial momentum of the left car?

d. What was the final momentum of the left car?

e. What was the final momentum of the right car?

A train is initially traveling due north at 25m/sec. Afternegotiating a curve, the train ends up traveling east at 20m/sec.The train's mass is 500,000 N and took 5.0 s to negotiate the turn.(Use north as the Y direction and east as the X direction)

A) What is the initial momentum vector for the train expressed interms of unit vectors?

B) What is the final momentum vector for the train expressed interms of unit vectors?

C) what is the change in momentum for the train?

A tennis ball initially moves with a velocity of 28.0 m/s horizontally to the right. A tennis racket strikes the ball, giving it a velocity of 28.0 m/s to the left. Treat the collision as elastic and the ball and racket as particles of mass 0.0580 kg and 0.261 kg respectively.
