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
Gravitational potential energy has changed from the beginning to the chain just sliding away from the table willl be MgL/24.
<h3>What is gravitational potential energy?</h3>The energy that an item has due to its location in a gravitational field is known as gravitational potential energy.
Length of hanging part, L/4
The gravitational potential energy is;
Work = Gravitational potential energy
Work done =force×displacement
Hence, gravitational potential energy has changed from the beginning to the chain just sliding away from the table willl be MgL/24.
