The speedboat B is cruising to the north at 76 mi/hr when it encounters an eastward current of speed vC = 20 mi/hr but does not change its heading (relative to the water). Determine the subsequent velocity of the boat relative to the wind and express your result as a magnitude vrel and compass direction θ measured clockwise from north. The current affects the motion of the boat; the southwesterly wind of speed vW = 27 mi/hr does not.
Car A is traveling at a constant speed vA = 143 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 5.1 m/s2 until a speed of 168 km/h is achieved, and that speed is then maintained. Determine the distance s required for the police officer to overtake car A. Neglect any nonrectilinear motion of P.
