Question

1.) How much potential energy does an object with a mass of 3 kg have on top of a stand 12 meters
high have on earth with a gravitational acceleration of 9.8 m/s, assuming no air friction?
a.) 3.673 Joules
b.) 352.8 Joules
c.) 39.2 Joules
d.) 2.45 Joules

Answer 1

Answer:

352.8 Joules

Explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

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

From the question we have

PE = 3 × 9.8 × 12

We have the final answer as

352.8 J

Hope this helps you
