Quiz 4 1. Two masses, with m? mi, reside on frictionless planks inclined at 30°·They are connected with a rope over a frictionless pulley. Find the acceleration of either mass. (o) m 8 m+ m mj m2 30 4 m2 mi (e) None of the above. 2. A mass m2 hanging vertically is connected by a rope and pulley to a mass mi, which sit on a horizontal table. The coefficient of kinetic friction for mi is 0.4. m2 is sufficiently large that mi slides as m2 descends. What is their common acceleration? (a) 11 g m1+ m2 m1 + mz m2 mi+ m2 mi+ (d) m1- m2 (e) None of the above.Explanation / Answer
