Chapter 11: Q. 4 (page 286)

A 0.2 kg plastic cart and a 20 kg lead cart can both roll without friction on a horizontal surface. Equal forces are used to push both carts forward for a time of 1 s, starting from rest. After the force is removed at t = 1 s, is the momentum of the plastic cart greater than, less than, or equal to the momentum of the lead cart? Explain

A 0.2kgplastic cart and a 20kglead cart can both roll without friction on a horizontal surface. Equal forces are used to push both carts forward for a distance of 1m, starting from rest. After traveling 1m, is the momentum of the plastic cart greater than, less than, or equal to the momentum of the lead cart? Explain.

Two 500gblocks of wood are 2.0m apart on a frictionless table. A 10g bullet is fired at 400m/s toward the blocks. It passes all the way through the first block, then embeds itself in the second block. The speed of the first block immediately afterward is 6.0m/s. What is the speed of the second block after the bullet stops in it?

A 100 g ball moving to the right at 4.0 m/s catches up and collides with a 400 g ball that is moving to the right at 1.0 m/s. If the collision is perfectly elastic, what are the speed and direction of each ball after the collision?

A 20 g ball is fired horizontally with speed v0 toward a 100 g ball hanging motionless from a 1.0-m-long string. The balls undergo a head-on, perfectly elastic collision, after which the 100 g ball swings out to a maximum angle ฮธmax=50ยฐ. What was v0?
