Impact Velocity and Coefficient of Restitution for a Tennis Ball Impacting a Tennis Racquet
by Mongkol Sukpraprut
Abstract
The impact and exit velocities of a tennis ball impacting on a fixed tennis racquet were measured with high speed video analysis to determine the coefficient of restitution (COR). It was found that there is a negative linear relationship between the COR and the impact velocity of the ball for velocities between 13 and 36 m/s.
