10.2: Surface Collisions and the Coefficient of Restitution

http://isjos.org/JoP/vol1/Papers/JoPv1i1-2Tennis.pdf WebJul 16, 2006 · The definition for the coefficient of restitution is: So if you know the KE before collision (KE0) you can find the KE after collision (KEf). This also works for multibody collisions where the KE's in the formula are the total KE for the system. By the way, you say you are looking for the velocity after collision. That isn't correct. send money to inmate in philadelphia https://sluta.net

Bounce of a tennis ball

WebTherefore, it is hypothesised that the coefficient of restitution of a tennis ball will be greatest on concrete. This is predicted because the tennis ball will bounce highest on the concrete, as the least amount of energy will be lost during the bounce. The reason is that the duration of contact will be smallest because the surface is the ... WebApr 12, 2002 · The COR for the superball studied was found to be 0.76 in the horizontal direction, and the corresponding COR for a tennis ball was found to vary from −0.51 to …

WebThe coefficient of restitution ( COR, also denoted by e ), is the ratio of the final to initial relative speed between two objects after they collide. It normally ranges from 0 to 1 where 1 would be a perfectly elastic collision. A perfectly inelastic collision has a coefficient of 0, but a 0 value does not have to be perfectly inelastic. WebFigure 1 shows the coefficient of restitution of a ball, at different impact velocities and on a rigid wall. Furthermore, in a tennis shot, ball deformation for a given velocity is affected …

WebThe coefficient of restitution between the tennis ball and the ground is 0.64. Determine distance d1. (include units with answer) Determine the magnitude of the velocity, v1, just after the first bounce. (include units with answer) Determine the angle of the This problem has been solved! WebOne of the requirements for tennis balls to be used in official competition is that, when dropped onto a rigid surface from a height of 100 in., the height of the first bounce of the ball must be in the range 53 in. ≤ h ≤ 58 in. Determine the range of the coefficient of restitution of the tennis balls satisfying this requirement.
