Question

A hemisphere S and a particle P are of same mass m = 72 kg. P is
dropped from a height 'h'. S is kept on a smooth horizontal surface. The
friction between P and S is also absent. P collides elastically with S at the
point shown in the figure. After collision the velocity of the particle becomes
horizontal. Find ratio of impulse of ground on hemisphere to speed of
hemisphere after collision ?​
