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 = 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 5.7 m/s? until a speed of 165 km/h is achieved, and that speed is then maintained. Determine the distance s required for the police officer to overtake car A. Answer:s= i

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.
