A 4.8 kg weight, mw, slides down a frictionless ramp that is at an angle of  = 22 with respect to the horizontal. The weight is attached to a massless string, which in turn is threaded over a pulley (solid disk) of radius rp = 4.5 cm and mass mp = 0.55 kg. The string is then wound around a thin hollow metal cylinder (hoop) of radius rc = 9.4 cm and mass mc = 8.6 kg. Assuming the wheel starts from rest, find its velocity after it has traveled a distance s = 15 cm down the ramp.

You are driving directly behind a pickup truck, going at the same speed as the truck. a crate falls from the bed of the truck to the road. (a) will your car hit the crate before the crate hits the road if you neither brake nor swerve? (b) during the fall, is the horizontal speed of the crate more than, less than, or the same as that of the truck?
