Question

The potential energy of a body is 39600 joules. How high is the body if its mass is 20kg

Answer 1

potential energy=mgh

mass=20kg

potential energy=39600J

g=10m/s^2

to find:height(h)

potential energy=20x10xh

39600=20x10xh

39600/20x10=h

height=198m

Answer 2

Answer:

mgh=39600 J

Mass=20 kg

g=10 m/s²

Height = ?

$mgh = 20 \times 10 \times h \\ 39600 = 20 \times 10 \times h \\ \frac{39600}{20 \times 10} = h \\ h = 198 \: m$

Height = 198 metre
