A 2.4 kg solid cylinder (radius = 0.20 , length = 0.55 ) is released from rest at the top of a ramp and allowed to roll without slipping. The ramp is 0.70m high and 5.0m long. when it reaches the bottom of the ramp:
what is the rotational kinetic energy?
what is the translational kinetic energy?
what is the kinetic energy?
Starting from rest, a 98 kg firefighter slides down a fire pole. The average frictional force exerted on him by the pole has a magnitude of 800N, and his speed at the bottom of the pole is 3.2 m/s. How far did he slide down the pole.
