The coefficient of restitution for a particular ball is 0.45. If he ball hits a surface traveling at 100 m/s its rebound speed will be
To find the rebound speed of the ball, we can use the formula for the coefficient of restitution (e):
e = (rebound speed)/(initial speed)
Given that the coefficient of restitution is 0.45 and the initial speed is 100 m/s, we can substitute those values into the formula and solve for the rebound speed.
0.45 = (rebound speed)/(100 m/s)
To isolate the rebound speed, we can multiply both sides of the equation by 100 m/s:
0.45 * 100 m/s = rebound speed
45 m/s = rebound speed
Therefore, the rebound speed of the ball will be 45 m/s.
