Consider again the system in Figure P9.14. Use the result from Problem 9.14 to find the acceleration of one of the crates. Hint: Is the acceleration constant?

(reference problem 9.14)

Two crates of mass and are connected by a rope that passes over a frictionless pulley of mass and radius 0.20 m as shown in Figure P9.14. (a) What force(s) can do work on the masses and the pulley? (b) Identify a system whose mechanical energy will be conserved. (c) The crates are released from rest. Crate 1 falls a distance of 2.0 m, at which time its speed is Make a sketch showing the initial and final states of the system. (d) What are the total initial and final kinetic energies of the system? Express your answers in terms of (e) What are the initial and final potential energies of the system? (f) What is the final speed of the crates? (g) What is the final angular velocity of the pulley?
