Question

Potential energy is a type of energy. Which of the following bricks has the most potential energy? a two-pound brick that is three feet off the ground a two-pound brick that is five feet off the ground a four-pound brick that is three feet off the ground a four-pound brick that is five feet off the ground

Answer 1

Answer:

Hey there!

Potential Energy = mgh, (mass x gravitational acceleration x height)

Given that the gravitational acceleration is constant, we just have Potential Energy = mh

a. 2(3)=6

b. 2(5)=10

c. 4(3)=12

d. 4(5)=20

The four-pound brick that is five feet off the ground is the brick with the most potential energy.

Let me know if this helps :)
