Explanation:
Step 1
As physics calculations requires all values to be done in decimals, start by converting
4/9mcolor(blue)(rArr)0.44m
Step 2
To find the gravitational potential energy, we can use the formula:
DeltaE_g
=E_"g,final"-E_"g,initial"
=mgh_f-mgh_i
=mg(h_f-h_i)
Since
Substituting the values into the formula,
=(5kg)(9.81m/s^2)(0.44m-0m)
=21.58J
