Question

What is the potential energy of a 150 kg diver standing on a diving board that is 10 m high?

Answer 1

Answer:

The potential energy is  14700J.

Explanation:

Definition of potential energy:

Potential energy is the energy that measures the ability of a object  to perform a job based solely on its position (height at which the object is from the ground), and it is calculated with the following formula:

Ep= m*g*h Formula (1)

Ep: Potential energy in Joules (J)

m : mass (kg)

g: acceleration due to gravity (m/s²)

h: height (m)

Data

m= 150 kg

g = 9.8 m/s²

h=  10 m

Problem development

We replace data in formula (1)

Ep=  150 kg*9.8 m/s²*10 m = 14700 N*m =  14700J

Ep=  14700J

Answer 2

W= F x dPower (formula)P= W/tForce (formula)F= m x anewton (N)the SI unit for force , equal to 1 kg*m/s2joule (J)the SI unit of work, equal to 1 newton-meter
