1. Two blocks shown in Fig. have masses A = 20 Kg and B = 30 Kg and the coefficient of kinetic friction between the block A and the horizontal plane, k = 0.25. If the system is released, from rest, and the block B falls through a vertical distance of 1m, what is the velocity acquired by it? Neglect the friction in the pulley and the extension of the string. 20 kg A B 30 Kg 2. A cricket ball, shot by a batsman from a height of 1.8 m at an angle of 30 with horizontal with a velocity of 18 m/s is caught by a fields man at a height of 0.6 m from the ground. How far apart were the two players ?
