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.

+51 suspension You are an engineer designing the suspension of an ATV. You want to ensure that the vehicle doesn't "bottom out" even when landing from being airborne. An approximation describing the vertical acceleration of the suspension upon impact is I a(s) 9.8(1 12s) m/s² where the initial velocity at impact is v=1.5 m/s with the spring initially uncompressed, s = 0 m A) What is the vertical velocity of the ATV chassis after the spring is compressed 0.1 m? B) What is the maximum distance the spring gets compressed? (This occurs when the ATV's vertical motion comes momentarily to rest)
