Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

A- The sports car has a mass of 2300 Kg and accelerates at 6 m/s, starting
from rest. If the drag resistance on the car due to the wind is FD (10 v) N,
where v is the velocity in m/s, determine the power supplied to the engine
when t = 5.s. The engine has a running efficiency ofɛ=0.68.
