hi, I apologize if this question is placed in the wrong area. I was not sure where it belonged. Can someone please help me with the following: Assuming the ice is very smooth, like that of your standard indoor hockey arena, how much much would an object have to weigh to remain stationary when hit with a 6oz puck traveling 100mph? 75mph? 50mph? and 25mph? I don't know if it matters, but the object being struck would smooth on the surface that touches the ice, and would be 72 inches wide, 4 inches deep, and 4 inches tall. Thank you in advance for any and all help you're able to provide! I appreciate you taking the time!
