Given:
m = 150 kg
h = 5m
g = 9.8m/s^2 ( acceleration due to gravity)
Determine the gravitational potential energy.
Formula for Gravitational Potential Energy:
Pe = mgh
Unit for Energy:
kg.m^2/s^2 = J
Solution:
Substitute the given values of m, g and h to the formula for gravitational potential energy.
Pe = mgh
Pe =(150 kg)(5m)(9.8m/s^2)
Pe = 7350 J
Final answer:
Pe = 7350 J
