Question

What is the mass of an object that is hanging 12 m above the surface of the earth and has a GPE of 3600 J?

Answer 1

Answer:

30

Explanation:

mgh =3600

m×120=3600

m=30kg

Answer 2

Answer:

Mass of object =m  =30.6 kg

Explanation:

Given:

Height of object from surface = h=12m

GPE = 3600J

Find out :

Mass of an object = m=?

SOLUTION:

Use Formula : GPE= mgh          (we know g=9.8m/s^2)

3600 = m(9.8)(12)

m=3600/117.6              (1J=kgm^2 s^2)

Mass of object =30.6 kg
