Car A is traveling at a constant speed VA = 120 km / h at a location where the speed limit is 100 km/h. The police officer in car P observes this speed via radar. At the moment when A passes P, the police car begins to accelerate at the constant rate of 5m/s^2 until a speed of 150 km / h is achieved, and that speed is then maintained. Determine the distance required for the police officer to overtake car A. Neglect any non- rectilinear motion of P.

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.
