Name:______________________________________ Physics 4A THIRD EXAM Chapters 1 - 12 Spring 1992 Solve the following problems in the space provided. Use the back of the page if needed. Each problem i worth 20 points. You must show your work in a logical fashion starting with the correctly applie physical principles which are on the last page. Your score will be maximized if your work is easy t follow because partial credit will be awarded. 1. In lab you examined a 50.0g ball moving at 6.00m/s colliding with a 200g pendulum arm with a cup a one end. The ball becomes imbedded in the cup and the pendulum arcs upward. Find (a)the velocity o the ball and pendulum arm just after the collision and (b)the height that the center of mass of the pendulum will rise. You may assume that there is no horizontal force exerted at the pivot point. m = 50.0g v = 6.00m/s M = 200g h = ? 2. A 1.00kg mass hangs from a string that is wrapped around a 3.00kg cylinder with a 5.00cm radius. After the mass is released
