Homework Help: Physics

Posted by Morgan on Sunday, March 7, 2010 at 6:41pm.

Okay, I saw this one previously posted, but the answer it kept leading me to was wrong.

A sports car of mass 1400kg (including the driver) crosses the rounded top of a hill (radius 88m) at 23 m/s. Find the normal force exerted by road on the car.

I thought that the normal force was mass times acceleration, just what the road is doing to the car. So I multiplied 9.8 times 1400, but that was wrong. What am i doing wrong? The same applies to a driver (weighing 75kg in the car)
