Answer;
98,000 joules
Explanation;
Kinetic is the energy possessed by a body in motion; while kinetic energy is the energy possessed by a body while at rest.
Potential energy is given by; mgh, where m is the mass, g the gravity, 9.8 m/s² and h is the height.
Energy can be transformed from one form to another and can neither be created or destroyed.
Therefore;
Potential energy = 2000 × 5 × 9.8
= 98,000 joules
Therefore, the kinetic energy will still be 98,000 joules, when the body is in motion.
