A collar of mass m is initially at rest on a horizontal arm when a constant moment M is applied to the system to make it rotate. Assume that the mass of the horizontal arm is negligible and that the collar is free to slide without friction.

Figure P5.88

Continue Prob. 5.87 by integrating the collar’s equations of motion and determine the time the collar takes to reach the end of the arm. Assume that the collar weighs 1.2 lb and that M = 20 ft·lb. Also, at the initial time let r0 = 1 ft and d = 3 ft.
