Assignment (To be submitted on 02/19/19) 1) Determine the initial acceleration of the 10-kg smooth collar. The spring has an unstretched length of 1 m.
2) If the supplied force F = 150 N, determine the velocity of the 50-kg block A when it has risen 3 m, starting from rest.
3) The 2-lb collar C fits loosely on the smooth shaft. If the spring is unstretched when s = 0 and the collar is given a velocity of 15 ft/s, determine the velocity of the collar when s = 1 ft.
