Answer:
3168 J
Step-by-step 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 10 m/s²
From the question we have
PE = 66 × 10 × 4.8 = 3168
We have the final answer as
3168 J
Hope this helps you
