Question

A sled is at rest at the top of a 2 m high slope. The sled has a mass of 45 kg. The sled's potential energy isJ. (Formula: PE = mgh) hurry please

Answer 1

Data:

h = 2m
m = 45 Kg
PE = ? (Joule)

Adopting, gravity (g) ≈ 9,8 m/s²

Formula:
`PE_(grav) = mass * g * height`

Solving:


`PE_(grav) = mass * g * height`

`PE_(grav) = 45*9,8*2`

`PE_(grav) = 882J`

Answer:
The sled's potential energy is 882 Joules
