A metal ball is moving with velocity $10\text{m/s}$ in downward direction as shown in the figure. After collision with a surface having coefficient of restitution $\left(e\right)=0.6$, it rebounds back. Find the rebound velocity. (Assume the surface remains stationary)

Q. A metal ball is moving with velocity $10\text{m/s}$ in downward direction as shown in the figure. After collision with a surface having coefficient of restitution $\left(e\right)=0.6$, it rebounds back. Find the rebound velocity. (Assume the surface remains stationary)

Q. A ball moving with velocity $10m/s$ in downward direction as shown in figure. After collision with fixed surface having coefficient of restitution $e=0.5$, it rebounds back with velocity $v\text{m/s}$. Find the value of $v$. (Neglect all external forces)

Q. A ball is moving with speed $3\text{m/s}$ in downward direction and the surface is moving with a constant speed of $2\text{m/s}$ upwards as shown in figure. After collision with the surface of coefficient of restitution $e=0.8$, the ball rebounds back with speed $v\text{m/s}$. Find the value of ${}^{\prime }{v}^{\prime }$. (Assume the surface doesn't change its velocity)

Q. A ball is moving with a velocity of $8\text{m/s}$ towards a surface which is also moving in a downward direction with velocity of $2\text{m/s}$ as shown in figure. After collision with the surface, ball rebounds back. If the coefficient of restitution is $e=0.5$, find the rebound velocity of the ball. (Given:Velocity of surface will be same even after collision and all other external forces are absent.)

Q. A ball initially at rest falls from a height $h=2.5\text{m}$. After collision with surface having value of coefficient of restitution $e=0.6$, it rebounds back. Find the rebound velocity of ball.
