A 1.5 kg block is connected by a rope across a 50-cm-diameter, 2.0 kg pulley, as shown. There is no friction in the axle, but there is friction between the rope and the pulley; the rope doesn’t slip.

Problem: A block is resting on a ramp as shown in the figure below. You can change the inclination angle θ by raising one end of the ramp. The block has a mass mb=6.5 kg. At the interface between the ramp and the block, the coefficient of static friction is μs=0.4, and the coefficient of kinetic friction is μk=0.28. I managed to calculate that: slip angle is θ= 21.8 degrees acceleration is 1.09 m/s^2. I am trying to find: 1. how long does it take from the time it slips to travel a distance d=0.95 m down the ramp?
