Answer:
Explanation:
When we lift a ball with the hand the forces experienced by the ball is
Resultant of these forces gives acceleration to the ball
While your hand exerts a force on the ball, the ball will also exert a force of equal magnitude but opposite in direction to the force by hand.
All these forces is exerted on the ball, hand or on the earth.
Longitudinal wave hope this is right :))))))))))
Hey wats there answerssssssssssssss need it nowwwwwwww ASAP !!!!!!!
<u>Answer:</u>
The height of the cliff in meters = 27.44
<u>Explanation:</u>
The potential energy of a body is given by the expression, PE = mgh, where m is the mass of the body, g is the acceleration due to gravity value and h is the height of the body.
Here we have mass of rock = 13 kg
Potential energy = 3500 J
Acceleration due to gravity = 
Substituting 3500 = 13 * 9.81 * h
h = 27.44 meter
The height of the cliff in meters = 27.44
