Question

Consider a system of a cliff diver and the Earth. The gravitational potential energy of the system decreases by 28,000 J as the diver drops to the water from a height of 40.0 m. Determine her weight in newtons.

Answer 1

700 N

Step-by-step explanation:

The gravitational potential energy of the system decreases by 28,000 joules

The diver jumps from a height of 40 meters

Therefore the weight in Newton can be calculated as follows

= 28,000/40

= 700 newtons
