Question

A 25.1 kg boy climbs to the top of a 11.08 m tall water slide at an amusement park. He carries a 2.94 kg rubber ball with him. Taking the bottom of the slide to be the zero point, what is the gravitational potential of just the boy in joules? (do not include units)

Answer 1

3080

Step-by-step explanation:

Potential energy is the energy stored or contained in a body as a result to its relative position to other objects, an example is an object that is placed at a height above the ground thereby experiencing gravitational energy.

Potential energy = mass × gravity × height

Given that: height = 11.08 m, gravity = 9.81 m/s² and mass = mass of boy + mass of ball = 25.1 + 2.94 = 28.34 kg

Potential energy =28.34 × 9.81 × 11.08 = 3080
