Name:______________________________________ Physics 4A THIRD EXAM Chapters 1 - 12 Fall 1993 Solve the following problems in the space provided. Use the back of the page if needed. Each problem is worth 20 points. You must show your work in a logical fashion starting with the correctly applied physical principles which are on the last page. Your score will be maximized if your work is easy to follow because partial credit will be awarded. 1. Two blocks of masses M and 3M are placed on a frictionless tabletop. They are tied together with a compressed spring between them as shown on the left. When the string is cut, the 3M mass moves to the right with a speed of 2.00m/s as shown below. Find the speed of the block of mass M. 2. A device for measuring the rotational inertia I of an object is shown. The object (not shown but assume it is there) should be placed on top of a shaft of diameter D and mass m that has a string wrapped around it. The string is connected to a hanging mass M which falls a distance h in a time t. Find the equation for the rotational inertia of the object in
