# Keep shooting !!

A gun which fires small balls of mass 20 g is firing 20 balls per second on the smooth horizontal table surface ABCD . If the collision is perfectly elastic and balls are striking at the centre of table with a speed of 5m$$s^{-1}$$ at an angle of 60° with the vertical just before collision ,then force exerted by one of the legs on ground is ?

(Assume total weight of the table is 0.2kg)
