Question

Jenny is playing on her spring bed, jumping up and down. She weighs 480.N, and her spring bed has springs with spring constant 1100N/m. What is the gravitational potential energy he will reach when she jumps to .32m?

Answer 1

153.6 J

Step-by-step explanation:

Weight, mg = 480 N

height jumped, h = 0.32 m

g = 9.8 m/s^2

Gravitational potential energy

U = m x g x h

U = 480 x 0.32

U = 153.6 J

Thus, the gravitational potential energy is 153.6 J.
