Kinetic Energy rotational motion problem, help please!
A 2.4 kg cylinder (radius = 0.11 m, length = 0.50 m) is released from rest at the top of a ramp and allowed to roll without slipping. The ramp is 0.62 m high and 5.0 m long.
(a) When the cylinder reaches the bottom of the ramp, what is its total kinetic energy?
(b) What is its rotational kinetic energy?
(c) What is its translational kinetic energy?
klinear = 1/2mv^2
krotation = 1/2Iw^2
tried plugging in 2.4 for mass but have no clue how to get the speed, when its not given.
