A small solid cylinder of mass
M and radius
R slides down a smooth curve from height
h. It gets onto plank of mass
M, which is resting on a smooth surface. If
μ is coefficient of friction between cylinder and plank, the time at which that cylinder attains pure rolling on plank is found to be
v0xμg where
v0=√2gh.
The value of
4x is
(Assume plank has sufficient length for cylinder to attain pure rolling)
