A ball falls on the ground from a height of 2.0 m and rebounds up to a height of 1.5 m. Find the coefficient of restitution.
Let the velocity of the ball when it approaches the ground be u
And v is the velocity of the ball when it separates from the ground.
Since,
Where g is the acceleration due to gravity and h is the height.
Therefore,
And
Now,
Where, l is the coefficient of restitution.
