Marks: 40 Do not write on the question paper. Write your SNU ID and Department in the front page of the answer sheet. 1) (i) A string with constant tension Tis deflected through angle 289 by a smooth fixed pulley. What is the force on the pulley [Fig.1]? {] - Fig.1 (ii) A horizontal friction less table, as shown in the sketch [Fig.2]. The angle of the wedge is @ and its height is 4. How the accelerations of the block and the wedge are related (hint use geometry)? (2] (iil) A drum of major’s baton consists of two masses m, and m separated by a thin rod of length /. The baton is thrown into the air, Find the equation of motion for the center of mass (é.e. acceleration of center of mass). {2} (iv) A rubber ball of mass 0.2 kg falls to the floor. The ball hits with a speed _ of 8m/s and rebounds with approximately the same speed. High speed Photographs show that the ball is in contact with the floor for At = 1073 s.
