Question

If Sophie climbs a ladder 3.4 m tall, and Sophie has a mass of 48 kg, how much G.P.E. has she gained?

Answer 1

Sophie gained 1,599.36 J of GPE

Step-by-step explanation:

Gravitational Potential Energy (GPE)

Gravitational potential energy is the energy stored in an object because of its vertical position or height in a gravitational field.

It can be calculated with the equation:

U=mgh

Where:

m = mass of the object

h = height with respect to a fixed reference

g = acceleration of gravity (
`9.8 m/s^2`)

Sophie has a mass of m=48 Kg and climbs a ladder that takes her to a height of h=3.4 m.

Calculate the GPE she gained:

U = 48 * 9.8 * 3.4

U = 1,599.36 J

Sophie gained 1,599.36 J of GPE
