A car drives over the top of a hill that has a radius of 50 m. What maximum speed can the car have at the top without flying off the road?

Answer:- The maximum speed of the car on top of hill is 19.8 m/s.

The agreed parameters;

radius of the hill, r = 40 m

The supreme speed of the car on top of hill is intended as follows;

the centripetal force must be equal or greater than weight of the car.

Therefore, the maximum speed of the car on top of hill is 19.8 m/s.
