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 5 m//s 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 0.2 kg )
