a 3 kg steel ball

Calculate the kinetic energy of a 7.3 kg steel ball travelingat 18.0 m/s. please show formula,what each number means in regards to theformula,and how to solve. thanks. Best Answer. This is the best answer based on feedback and ratings. (1 rating)...Here's how the calculation works: Volume = (3.142 x (0.025 x 0.025)) x 1. Volume = 0.00196m3. Stainless Steel Type 304 Density = 7930 kg/m3. If we multiply the 0.00196m 3 volume figure by the 7930 kg/m 3 density figure, we end up with a weight of 15.54 kg or 34.26 lbs.

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)
