A solid cylinder of mass 2.5kg and radius 0.15m starts from rest and rolls without slipping down a straight ramp that is 5.0m long and 1.8m high. While it moves, a constant 3.0N resistive force acts opposite its motion along the ramp. Calculate the speed of the cylinder’s center of mass at the bottom of the ramp. (Use g=9.8m/s2.)
