Answer:
Potential energy = 73.575 kJ
Kinetic energy = 135kJ
Total mechanical energy = 208.575 kJ
Explanation:
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.
The kinetic energy of a body is given by , where v is the velocity and m is the mass of body.
Total mechanical energy = Kinetic energy + Potential energy
PE = mgh = 75*9.81*100 = 73575 J = 73.575 kJ
Total mechanical energy = Kinetic energy + Potential energy = 135+73.575
= 208.575 kJ
