Answer:
Kinetic energy = 135 kJ
Potential energy = 73.5 kJ
Explanation:
Mass of sky diver = 75 kg
Velocity = 60 m/s
Height = 100 m
Kinetic energy is given by the expression,
, where m is the mass and v is the velocity.
So Kinetic energy = 
Potential energy is given by the expression, PE =mgh, m is the mass, g is the acceleration due to gravity value and h is the height.
So, Potential energy = 75*9.8*100 = 73500J = 73.5 kJ
