Answer:
Explanation:
The speed of the actor before the collision is found by means of the Principle of Energy Conservation:
The speed after the inelastic collision is obtained by using the Principle of Momentum Conservation:
Lastly, the maximum height is determined by using the Principle of Energy Conservation again:
Since velocity is vector quantity, it'll depend on both direction as well as magnitude hence options C and D are rejected.
Speed = distance/time
Therefore, unit of velocity is m/s.
