3) A crate of mass of mass 180.0 kg is pushed with intial speed of 33 m/s along a concrete floor. If the crate comes to rest after covering 35 m, determing the coeficient of kinetic friction between thecrate and the floor. A B D E 0.476 0.615 0.492 0.532 0.435 3) A 1700 kg car decending a hill of height 250 m with a speed of 45 m/s suddenly loses power. The breaks fail as a result and the driver steers the car carefully down the hill to reach the level ground. With no brakes, the car continues on the level ground and eventually comes to rest after a distance of 1600 m. Determine the magnitude of the force responsible for stopping the car. Assume the driver's mass to be included in that of the car. E 4528 N A 4905 N H = 250 m B 4204 N Vo C 3924 N D 3679 N
