Given:
mass = 4 kg
height = 2 m
acceleration due to gravity = 9.8 m/s^2
Determine the gravitational potential energy.
Formula for Potential Energy:
PE = mgh
Solution:
Substitute the given values of mass, height and acceleration due to gravity in the formula for acceleration due to gravity.
PE = mgh
PE = (4kg)(2m)(9.8 m/s^2)
PE = 78.4 J
Final answer:
PE = 78.4 J
