Question

A 87 kg person sits at rest at the top of a 51m high amusement park ride. How much energy does the person have at this point

Answer 1

We will calculate potential energy, in this case, using the next formula

`PE=\text{mgh}`

where m is the mass, g is the gravity and h is the height

in our case

m=87 kg

g=9.8 m/s^2

h=51m

we substitute

`PE=87(9.8)(51)=43482.6J`

ANSWER

The energy is 43482.6J
