- James realizes that he can try to get Kevin by having two balls roll down from opposite hills. Ball one is 15kg and is being rolled down a hill of height 32m, ball two is 20kg, and is rolling down in the opposite direction from a height of 18.5m. What are their final velocities at the bottom of the hill? If they are now on a flat plane and collide in a completely elastic collision, what are their final speeds after the collision? (SHOW ALL WORK, UNITS AND FORMULAS USED)Three identical train cars, coupled together, are rolling east at speed v0v0. A fourth car traveling east at 2v0v0 catches up with the three and couples to make a four-car train. A moment later, the train cars hit a fifth car that was at rest on the tracks, and it couples to make a five-car train.What is the speed of the five-car train?please help me with this problem. Given: A ball of clay mass M/8 A larger mass as known as M is attached to a spring with spring constant k. A ball of clay mass "M/8" moves with speed "v" towards a larger mass M. As the a ball of clay hit and sticks on the a larger mass who was initially still. a) What would be the speed of the combination after the collision? b) How much did the spring compressed c) How long did it take for the spring to be compressed due to the collision?
