Answer 2_5_6

What is the potential energy of a 12 kg mass raised to a height of 25 m?

Potential Energy = weight x height change

Weight = 12 kg x 10 N/kg = 120 N

Height change = height at end - height at start = 25 - 0 = 25 m

Potential energy = 120 N x 25 m = 3000 J

 

Did you fall into the bear trap of using weight as kilograms?
