l3 A 95 g projectile is launched at a speed of 22 m/s. It strikes a 1.7 kg stationary ball of clay, and becomes embedded in the clay. How fast does the combined projectile-clay unit travel immediately after the collision? Two train cars are about to link together. CarA has a mass of 76, 000 kg, and is traveling north at a speed of 0.55 m/s. Car B has a mass of 33, 000 kg, and is traveling south at a speed of $1.9$' m/s. After they connect, what will be the velocity of the combined unit? Kayla and Jasmine are sledding down a hill. Kayla, who has a mass of 34 kg and a velocity of 7.9 m/s in the positive direction, is directly behind Jasmine, who has a mass of 27 kg and a velocity of 5.4 mfs in the same direction. When Kayla collides with Jasmine, Kayla's velocity drops to 4.8 m/s. What is Jasmine's velocity immediately after the collision? Jamison is playing pool. He strikes a 170 gram cue ball so that it moves at a velocity of 5.9 m/s in the positive m-direction. The cue ball, in turn, strikes a stationary 160 gram numbered ball so that it travels with a velocity of 5.4 m/s in the positive m-direction. What is the velocity of the cue ball immediately after the collision? Two shipping packages are sliding down a smooth table, in the positive direction. Package A has a mass of 12 kg, and a velocity of 6 m/s. Package B has a mass of 8 kg, and a velocity of 10 m/s. If the packages were to collidE, which of the following sets of velocities would conserve momentum? Two people are running south. The rst person has a mass of 66 kg, and is running at a speed of 5.1 m/s. The second person has a mass of 74 kg, and is running at a speed of 4.7 m/s. If these two people were to collide, what would their combined momentum be after the collision
