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?

Sophie gained 1,599.36 J of GPE

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 ()

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

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.
