Question:
The log has mass M and rests on the ground for which the coefficients of static and kinetic friction are μs and μk respectively. The winch delivers a horizontal towing force T to its cable at A which varies as shown in the graph. Determine the speed of the log when t = t2. Originally the tension in the cable is zero.
