Q2. Car A is traveling at 25 mi /hr and applies the brakes at the position shown so as to arrive at the intersection C at a complete stop with a constant deceleration. Car B has a speed of 40 mi /hr at the instant represented and is capable of a maximum deceleration of 18 ft /sec2. If the driver of car B is distracted, and does not apply his brakes until 1.30 seconds after car A begins to brake, the result being a collision with car A, with what relative speed will car B strike car A? Treat both cars as particles. (10 degrees) 60- -120-

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.
