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?
