A 60-lb block is connected by an inextensible cable through the pulley to the fixed surface, as shown in Figure P1.12. A 40 lb weight is attached to the pulley, which is free to move vertically. A force of magnitude P = 100(1 + e -t) b tows the block. The system is released from rest at t = 0.
(a) What is the acceleration of the 60 lb block as a function of time?
(b) How far does the block travel up the incline before it reaches a velocity of 2 ft/s?
