If a ball hits a wall going 10 m/s, and bounces off going 7 m/s. What is the coefficient of restitution?
To find the coefficient of restitution, we need to use the formula:
Coefficient of Restitution (e) = (Final Velocity after bounce) / (Initial Velocity before bounce)
In this case, the initial velocity before the bounce is 10 m/s and the final velocity after the bounce is 7 m/s.
Coefficient of Restitution (e) = 7 m/s / 10 m/s
To find the answer, we can divide 7 by 10.
Coefficient of Restitution (e) = 0.7
Therefore, the coefficient of restitution is 0.7.
