Question

A 60-kg suitcase slides from rest 5 m down the smooth ramp. The suitcase has an initial velocity down the ramp of vA = 1.1 m/s , and the coefficient of kinetic friction along AC is μk = 0.2. (Figure 1)

A) Determine the distance R where it strikes the ground at B.

B) How long does it take to go from A to B?
