Answer:
the velocity (magnitude and direction) of the ball) just before the collision is
The velocity (magnitude and direction) of the ball) just after the collision is
Explanation:
According to the law of conservation of energy;
Thus; the velocity (magnitude and direction) of the ball) just before the collision is
Since, Air resistance is negligible, and the collision is elastic.
The equation for the conservation of momentum and energy can be expressed as:
The velocity (magnitude and direction) of the ball) just after the collision is
