An 1800 kg car passes over a hump in a road that follows the arc of a circle of radius 42 m.(adsbygoogle = window.adsbygoogle || []).push({});

a. What force does the road exert on the car as the car passes the highest point of the hump if the car travels at 16 m/s?

b. What is the maximum speed the car can have as it passes this highest point before losing contact with the road?

Now for my work

a.

F = ma

F = mv²/r

F = (1800)(16²)/42

F = 10971.4 N

I think that is horribly wrong in my opinion... and also I have no idea how to start question b. No pictures or anything either
