Answer:

27,440 J

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 = 1400 × 9.8 × 2

We have the final answer as

27,440 J

Hope this helps you
