A rollercoaster starts at a height of 30m above the ground. At the bottom of a loop. The rollercoaster is at a height of 10m. Approximately, how much gravitational potential energy is lost by a 75kg rider?

A19.6 joules. Eliminate.
B1470 joules.
C14,700 joules
D22,050 joules

Gravitational potential energy is calculated by multiplying mass, height and the acceleration due to gravity.

Gravitational potential energy = mgh
Gravitational potential energy = 75 kg (9.8 m/s^2) ( 30 m)
Gravitational potential energy =22050 joules

Therefore, the correct answer is option D.
