km hr Q3/ Vehicle A is moving at a constant velocity VA 120- at a location where the speed limit is 100 km/h. The police officer in vehicle P observes this speed via radar. At the moment when A passes P. the police car begins to accelerate at the constant rate of 5 until a speed of 140 km/hr is U achieved, and that speed is then maintained. Determine the distance required for the police officer to overtake car A. TU- ENGINEERING COLLEGE- ALSHIRQAL

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.
