###### 1.Car A experienced engine failure the moment it enters a 2-km highway that has a constant grade of 4 deg throughout its span (4 deg. inclination). Point C is the location where car A experienced failure. When car A is towed by the truck it gains an acceleration of 3 m/s^2, at the same instance, car B is passing the same highway with a constant velocity of 40 km/hr and is 100m away from point C (measured along the pavement). a) At what time will car A overtake car B? answer in unit of seconds.b)
