Homework Statement
A 2.7kg solid sphere (radius .2m) is released from rest at the top of a ramp and allowed to roll without slipping. The ramp is .5m high and 5.4 long.
When the sphere reaches the bottom of the ramp what is the rotational kinetic energy and the translational kinetic energy.
Homework Equations
krotf=1/2(2/5mr^2)wf^2
ktransf=1/2mvf^2
The Attempt at a Solution
krotf=1/2(2/5(2.7)(.2^2))wf^2
ktransf= 1/2(2.7)vf^2
