Question

A rock with mass of 5.0 kg is carried up a small hill 10 meters high. What is the potential energy of the rock at the hilltop?

Answer 1

490J

Step-by-step explanation:

Given parameters:

Mass of rock = 5kg

Height of hill = 10m

Unknown:

Potential energy at the hilltop = ?

Solution:

Potential energy is the energy at rest of a body. it is given as:

                P.E = mgh

m is the mass of the body

g is the acceleration due to gravity = 9.8m/s²

h is the height of the hilltop

     P.E = 5 x 10 x 9.8 = 490J
