Here is your answer.
A 975-kg sports car (including driver) crosses the rounded top of a hill (radius = 88.0 m) at 18.0 m/s. Determine (a) the normal
force exerted by the road on the car, (b) the normal force exerted by the car on the 62.0-kg driver, and (c) the car speed at which the normal force on the driver equals zero.

Here we will say that there is no external torque on the system so we will have
here we know that
where we know that
Also we know that
initial angular speed will be
now from above equation
now we have
so final speed will be 2.41 rad/s
Answer:
22.67 m/s
