Question

builder places a 3kg hammer on the top of a ladder, which is 4m above the ground. Calculate the gravitational potential energy of the hammer while on the ladder.

Answer 1

`E=mgh`

`m=3kg`

`h=4m`

`g=9.8m/s^(2)`

`E= 3*4*9.8=117.6J`

Step-by-step explanation:

Only substitute amounts to formula.

Hope this helps ;)

Cheers :D
