D Question 8 10 pts A block of mass m, = 24.8 kg lies on a rough table. The coefficient of static friction between the block and the table is , = 0.477. The block is connected to a mass my by means of a pulley as shown. What is the maximum mass my such that block m, is stationary? Give your answer in units of kg. 171 4 11.83 D Question 9 10 pts A 1500 kg elevator is descending. The tension in the elevator cable is 12,000 N. What is the magnitude of the downward acceleration of the elevator? This is a positive number. Give your answer in units of m/s?. D Question 10 10 pts A force of F = 66.6 # N acts on a block my = 12.5 kg. The force is angled at 33.3" with respect to the horizontal. The block lies on a flat surface and the coefficient of kinetic friction between the block and the surface is / = 0.333. What is the magnitude of the horizontal acceleration of the block? Give your answer in units of m/s2. m1
