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.

An airport shuttle train travels between two terminals that are 1.6 mi apart. To maintain passenger comfort, the acceleration of the train is limited to ±4 ft/s2 , and the jerk, or rate of change of acceleration, is limited to ±0.8 ft/s2 per second. If the shuttle has a maximum speed of 20 mi/h, determine (a) the shortest time for the shuttle to travel between the two terminals, (b) the corresponding average velocity of the shuttle.

Matching heights A stone is thrown with an initial velocity of32 ft/s from the edge of a bridge that is 48 ft above the ground.The height of this stone above the ground t seconds after it isthrown is ƒ(t) = -16t2 + 32t + 48. If a second stone is thrownfrom the ground, then its height above the ground after t secondsis given by g(t) = -16t2 + v0t, where v0 is the initial velocity ofthe second stone. Determine the value of v0 such that both stonesreach the same high point.
