The coefficients of friction between the 160-kg crate and the ramp are μs = 0.3 and μk= 0.28.

(a) What tension T0 must the winch exert to start the crate moving up the ramp?

---

(b) If the tension remains at the value T0 after the crate starts sliding, what total work is done on the crate as it slides a distance s = 3 m up the ramp, and what is the resulting velocity of the crate?
