Question

Calculate potential energy of a 5 kg object sitting on 3 meter ledge

Answer 1

Pe=5*9.8*3=147 joules

Answer 2

Answer:147 joules

Explanation:

Mass=m=5kg

Acceleration due to gravity=g=9.8m/s^2

Height=h=3 meter

Potential energy=m x g x h

Potential energy=5 x 9.8 x 3

Potential energy=147 joules
