Question

find the potential energy of a body of mass 2kg resting at a height of 2 metre ( take g equal to 9.8 metre per second square).​

Answer 1

Answer:

PE = 39.2 Joule

Explanation:

Mass = 2kg

Height = 2m

Acceleration Due to Gravity (g) = 9.8 m/s²

Potential Energy (PE) = Mass × g × Height

PE = 2 × 9.8 × 2

PE = 4 × 9.8

PE = 39.2 J
