# Normal Force

#### briiannnaa04

1. The problem statement, all variables and given/known data
a 1,000 kg car coasts into a slight dip in the road. The radius of the dip is 200-m. At the bottom of the dip the speed of the car is 10 m/s.
what is the magnitude and dirrection of the normal force?

2. Relevant equations
Sum of f=ma to find acceleration.

3. The attempt at a solution
the acceleration would be .5 m/s/s so wouldnt it just be .5*1000
the answer says it should be 10300 though.

there is the normal force acting as well as weight. The resultant of these two provide the centripetal force, mv2/r

Write down the resultant force in terms of the normal reaction and the weight
