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 for the collision between the ball and the surface of the tunnel is 0 2 then the distance travelled nR by the ball before the second collision at the centre is Find the value of n S
