What is the kinetic energy of the ball just before it hits the ground?
1 answer:
Answer:
Explanation:
Kinetic energy,
while potential energy, PE= mgh where m is the mass, v is the velocity of the ball, g is acceleration due to gravity and h is the height.
The question requires kinetic energy hence we use the
Since the figures are not given, we maintain that
