1) What is the impulse due to a force rthat causes the speed of a 46 g golf ball to change from 0 to 60.0 m/s in 0.50ms?
2) A 0.250 kg ball of Plasticine moving 5.0 m/s overtakes and collides with a 0.3000 kg ball of Plasticine, traveling in the same directiion at 2.0 m/s. The 2 balls of Plasticine stick together pm collison. What is their speed after the collision.
3) A 4.2 kg rifle shoots a 0.05 kg bullet at a speed of 3.00 * 10^2 m/s. At what speed does the rife recoil?
4) A railroad car of mass 12,000kg is traveling at a speed of 6.0 m/s when it collies with an identical car at rest. Thte two cars look together. What is their common speed after the collision?
5) What impuse is needed to change the speed of a 10 kg object from 1.6 m/s to 25.5 m/s in a time of 5s. How much force is needed?
