The crate has a mass of 120 kg, and the coefficients of friction between it and the sloping dock are μs = 0.6 and μA = 0.5
(a) What tension must the winch exert on the cable to start die stationary crate sliding up the dock?
(b) If the tension is maintained at the value determined in part (a), what is the magnitude of the crate’s velocity when it has moved 2 m up the dock?
