Question 1.2 A crate of mass, mi, sits on a rough surface and is connected by a rope over a pulley to a second mass, m2, hanging over a cliff. The surface has coefficient of friction, u. The two masses are initially held at rest. Rope mass, pulley mass and pulley friction can be neglected. a) Draw free body diagrams for the elements of the system. [6 marks) b) What is the acceleration that occurs when the masses are allowed to move? [10 marks) c) What is the velocity after m, has fallen by a distance, h? Assume that my remains on the surface and does not reach the cliff. [4 marks] та = = m = 15 kg m2 = 10 kg H = 0.4 h = 5 m m2 Total for
