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.

Your answer is partially correct. Airplane A is flying horizontally with a speed of 218 km/h which is increasing at the rate of 4.8 km/h each second and is towing the glider B, which is gaining altitude. If the tow cable has a length r = 80 m, and the cable is unreeling at the constant rate r = 1.8 m/s while 0 = 19° is kept constant, determine the magnitudes of the velocity v and acceleration a of the glider.

Car A is traveling at a location where the speed limit is 100 km/h. The police officer in car P observes this speed via radar. The driver of car A is traveling at VA = 126 km/h as it passes P, but over the next 4.2 seconds, the car uniformly decelerates to the speed limit of 100 km/h, and after that the speed limit is maintained. At the moment when A passes P, the police car begins to accelerate at the constant rate of 4.1 m/s² until a speed of 155 km/h is achieved, and that speed is then maintained. Determine the distances required for the police officer to overtake car A. A Answer: s= i DA P m
