1. Draw an arrow showing the direction of the force on the car at A
2. Draw an arrow showing the direction of the velocity.
3. If the car hit an ice patch at point B, draw an arrow showing which way the car will go.
4. If the car drives twice as fast, how much more centripetal force is needed to go in a
circle?
