Question

A 150 g cricket ball is hit by a batsman with an initial
velocity of 40 m/s at an angle 60° with the horizontal. Find
its kinetic energy when it reaches its maximum height.

Answer 1

Answer:

Kinetic energy at maximum height is zero.

Explanation:

Given:-

Mass of ball, m = 150 g

Velocity of ball, v = 40 m/s

Angle, ∅ = 60°

To find the kinetic energy at the maximum height.

Now, we know that at the maximum height, the velocity of the ball will be zero implying that the ball will no more be in motion.

Therefore, the kinetic energy of the ball at the maximum height is zero.
