Nhat is the kinetic energy of an object that has a total mechanical energy of 00 J and potential energy of 20 J? 5J o 2000 Din 80J D 120J

The total mechanical energy of an object is the sum of its kinetic energy and potential energy. Given that the total mechanical energy is 100 J and the potential energy is 20 J, we can find the kinetic energy using the formula:<br /><br />Kinetic Energy = Total Mechanical Energy - Potential Energy<br /><br />Substituting the given values:<br /><br />Kinetic Energy = 100 J - 20 J = 80 J<br /><br />Therefore, the kinetic energy of the object is 80 J.
