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 … WebHere is the equation for the coefficient of restitution. e = √ hb / hd. Coefficient of restitution= the square root of the height of the bounce divided by the height of the drop. For this project we measured the COR of a Titlelist 4 golf ball. We dropped the ball from a height of 1.24m five times to get a consistent height of the bounce.
WebA ball is dropped from a height h on a floor of coefficient of restitution e. The total distance covered by the ball just before the second hit is ... The tennis ball bounces to a height …
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. WebThe coefficients of restitution vary according to the ball used; the tennis ball had the highest value (e = 0.82) and the cricket ball the lowest value (e = 0.48). This means the tennis ball bounced much higher than the …
WebA tennis ball is served horizontally from a height of 7.5 ft with a speed of 71 ft/s. The coefficient of restitution between the tennis ball and the ground is 0.68. A) Determine …
