The crate, which has a mass of 120 kg, is subjected to the action of the two forces.  If it is originally at rest, determine the distance it slides in order to attain a speed of 9 m/s. The coefficient of kinetic friction between the crate and the surface is μk = 0.2. Express your answer to three significant figures and include the appropriate units.

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.
