Question

Find the mass of an object that has 147J of potential energy sitting on a 3m ledge. I don’t understand this. Help quick! ;^;

Answer 1

Answer: m = 5 kg

Explanation: To solve for the mass of the object we will use the formula of Potential energy

PE = mgh. Derive for mass, so the formula will be

m= PE / gh

m = 147 J / 9.8 m/s² ( 3 m )

= 5 kg
