Question

A body of mass 30kg is suspended at a height of 12m from the ground. What is the potential energy of the body at this height? (g=10m/s2)

Answer 1

Answer:

Explanation:

potential energy is mass x gravity x height

which is 30kg x 10m/s x 12m

this equals 3600 Joules

Hope this helped

Answer 2

We know that

$p.e \: = mgh$

given that

m=30 kg

$g = 10 {ms}^{ - 2}$

h = 12m

$p.e \: = (30)(12)(10)$

$p.e = 3600j$
