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.

Their speeds are Va= 65 mi/h and Vb= 40 mi/h, and they are at points P and Q, respectively. knowing that A passes point Q 40s after B was there and that B passes point P 42s after A was there: A) determine the speed of B at the moment that it passes A in ft/s B.) when the vehicles pass each other in seconds C.) uniform acceleration of B in ft/s^2
A motorcycle patrolman starts from rest at A two seconds after a car, speeding at the constant rate of 120 km/h, passes point A. If the patrolman acceler- ates at the rate of 6 m/s² until he reaches his maxi- mum permissible speed of 150 km/h, which he maintains, calculate the distances from point A to the point at which he overtakes the car. 120 km/h
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. VA A Answers: V = a = i 58.8 1.33 km/h m/s²
Car A is traveling at a location where the speed limit is 100 km/h. The police officer in car Pobserves this speed via radar. The driver of car A is traveling at VA = 138 km/h as it passes P, but over the next 4.3 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 5.0 m/s² until a speed of 167 km/h is achieved, and that speed is then maintained. Determine the distances required for the police officer to overtake car A. Answer: s= i m
