Question

the potential energy of a body is 39600 j, how high is the body if its mass =30 kg, g=10m/s-²​

Answer 1

Answer:

the mass of body is 132 ... potential energy=mgh

Answer 2

Answer:

13.2 m  

Explanation:

Given,

PE = 39600 J

mass = 30 kg

g = 10 m/s^2

we know that,

PE = mgh

39600 = 300 × 10 × h

39600 = 3000h

h = 39600/3000

h = 13.2 m
