Answer:
the potential energy is 114 J.
Explanation:
Given;
total mechanical energy, E = 400 J
kinetic energy, K.E = 286 J
The potential energy is calculated as follows;
E = K.E + P.E
where;
P.E is the potential energy
P.E = E – K.E
P.E = 400 J – 286 J
P.E = 114 J
Therefore, the potential energy is 114 J.
