A small spherical ball is released from a point at a height h on a rough track shown in figure (10-E13). Assuming that it does not slip anywhere, find its linear speed when it rolls on the horizontal part of the track.
Let the mass of the small ball = m
The velocity of the ball = v
Radius of the ball= R
Let it reaches to the height = h
Since the surface is rough, the sphere does not slip,
Potential energy of the sphere converts into angular kinetic energy and liner kinetic energy
Hence, we can write,
