Natural force of circular motion

[peweee17]

Homework Statement

A 950kg sports car (including driver) crosses the rounded top of a hill (radius = 86.0m) at 10.0m/s.

Homework Equations

A. Determine the normal force exerted by the road on the car.
B. Determine the normal force exerted by the car on the 73.0kg driver.
C. Determine the car speed at which the normal force on the driver equals zero.

The Attempt at a Solution

I started to look at this problem like a loop da loop problem where there are different values of forces depeding on wether your on the top or bottom. Fn top= mg(((v^2)/rg)-1)
