Answer:

Step-by-step explanation:
Given
Mass of ball is M
Height of incline is H
Here conservation of energy will provide the velocity at bottom
Energy at top of incline plane

Energy at bottom=Kinetic energy+Rotational energy
Assuming Pure rolling we can write

where
=velocity of ball
=angular velocity of ball
R=radius of ball

where I=moment of inertia of ball



Now ,
