3: A 975kg car (mass includes the driver) crosses the rounded top of a hill (radius 88m) at 18 m/s.
a: What is the normal force exerted by the road on the car?
b: What is the normal force exerted by the car on 62kg driver?
c: At what speed does the normal force on the driver equal zero?
At the top of the hill , the normal force acts in upward direction while the weight of the car and the the centripetal force acts in downward direction.
Considering all force in vartical direction we can find the normal force.
