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?
A. 19.6 joules. Eliminate.
B. 1470 joules.
C. 14,700 joules
D. 22,050 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.
