Answer:
The value
Explanation:
From the question we are told that
The acceleration due to gravity is a = 2g
The maximum height is h= 39 m
Generally from the kinematic equation
Here u is the velocity of the ball at maximum height before it start falling and the value is 0 m/s
So
Kinetic Energy, or K.E is equal to 1/2 times the mass of an object times the velocity squared.
Therefore K.E
which is 225
Energy is expressed in joules (J)
so the K.E of the ball is 225J
