A car is traveling through a valley at a constant speed, though not a constant velocity and (I believe) it is at the bottom. If the car's speed is 25 m/s, its mass is 1200 kg and the radius of the valley (r) is 25 meters, Use your force diagram to create a Fnet=ma equation for the Y-Direction. Then determine the magnitude of the force of the road acting on the car. (i.e. the Force Normal)
m = mass; v = velocity; r = radius
The Attempt at a Solution
So I know the force body diagram. Fn (Normal Force) is greater than Fg (gravity).
Then when I continue to work with the equation I can come up with
Fg - Fn = (mv2)/r which then becomes
Fn = Fg - (mv2)/r
However after this step I don't know what to plug in or even how to solve for the numbers that need to be plugged in. Well gravity will be 11760 N but after that I am lost.
