A ball is dropped onto a horizontal floor. Reaches a height of `144 cm` on the first bounce and `81 cm` on the second bounce. Coefficient of restitution is

A ball is dropped onto a horizontal floor. Reaches a height of 144 cm on the first bounce and 81 cm on the second bounce. The height it attains on the third bounce is

A ball is dropped on a horizontal surface from height h. If it rebounds upto h/2 after first collision then coefficient of restitution between ball and surface is

A ball is dropped on a horizontal surface from height h. If it rebounds upto height (h)/(2) after first collision then coefficient of restitution between ball and surface is

A ball is dropped on a horizontal surface from height h. If it rebounds upto height (h)/(2) after first collision then coefficient of restitution between ball and surface is

A ball is dropped on a plane horizontal surface from height H. The ball bounces and reaches height h. Show that cofficient of restitution is e = sqrtfrac(h)(H)
