A city planner is working on the redesign of a hilly portion of a city. An important consideration is how steep the roads can be so that even low-powered cars can get up the hills without slowing down. A pariticular small car, witha mass of 1100kg, can accelerate on a level road from rest to 21m/s (75km/h) in 14,0s using these data, calculate the maximum steepness of a hill.
