Acar drives over the top of a hill that has a radius of 40 m. ? part a what maximum speed can the car have without flying off the road at the top of the hill?

Maximum speed = 19.81 m/s

Explanation:

Maximum speed can the car have without flying off the road at the top of the hill.

For this condition to occur we have

         Centripetal force ≥ Weight of car.

For maximum speed without flying we have

Maximum speed = 19.81 m/s

yup its correct its: c) b b

that would be because of both gravity and friction. so     c
