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

2) A body having a mass of 30 lbm is acted on by a force given by
F =
30t² + e ¹ lb
If the velocity is 10 ft/s at t = 0, what is the body's velocity and the distance
travelled when t = 2 seconds? Note: the unit "slug" is synonymous with lbm or
"pound-mass".
