F approx 78 N We know that the momentum before the collision would be the same as after it because of the conservation of momentum. This just means, though, that the change in momentum of the ball is matched by an equal change in momentum of the wall. The impulse, and therefore the force, will be determined by the change in the momentum of the ball. Due to the …...1500 kg 5/16 3/8 inch HRC 60-66 AISI 1086 carbon steel balls for milling make Chocolate Dongguan Lychon Hardware Co., Ltd. 50 Kilograms (Min. Order)
