Ek = 120 J.
Ep = 35 J.
А- ?
Mechanical energy, which includes kinetic Ek and potential energy En of a body, is a measure of how it performs mechanical work A. This means that the more a body has mechanical energy, the more mechanical work it can perform.
The body will do the maximum mechanical work And when it uses all its mechanical energy: A = Ek + En.
A = 120 J + 35 J = 155 J.
Answer: the body can perform the maximum mechanical work A = 155 J.
