A smooth tunnel is dug along the radius of the earth that ends at the centre. A ball is released from the surface of earth along the tunnel. If the coefficient of restitution is `0.2` between the surface and ball, then the distance travelled by the ball before second collision at the centre is

A smooth tunnel is dug along the radius of earth that ends at centre. A ball is relrased from the surface of earth along tunnel. Caefficient of restitution for collision between soil at centre and ball is 0.5 . Caculate the distance travelled by ball just second collision at center. Given mass of the earth is M and radius of the earth is R .

A ball is dropped from a height of 3m . If coefficient of restitution between the surface and ball is 0.5 , then the total distance covered by the before it comes to rest is

If a tunnel is dug along the diameter of the earth and a ball is dropped into the tunnel, it will have

A ball is dropped from a height h on a floor. The coefficient of restitution for the collision between the ball and the floor is e. The total distance covered by the ball before it comes to the rest.
