As shown in the figure, two boxes of mass and are connected by an essentially massless, non-elastic wire passing over a light, frictionless pulley. The box of mass m, is released from rest at height h above the table. Use the isolated system model to answer the following. (We assume m, > m,. Use any variable or symbol stated above along with the following as necessary: g.) (a) Determine the speed of m, just as m, hits the table. v= 5.77 Since the only force acting is the conservative force of gravity, mechanical energy is conserved. Write a statement of conservation of energy and the expressions for the change in kinetic energy and the change in gravitational potential energy. Combine these three expressions and solve for the speed in terms of known quantities. Note that you want the speed and not the velocity. (b) Find the maximum height above the table to which m, rises. hmax 6.66 The maximum height is the distance h plus Ah the distance m, travels upward after m, lands on the table. Since the only force acting on m, during this time is the conservative force of gravity, conserve mechanical energy to determine Ah.
