Recall that when we examined the motion of an object moving in a circle, at a constant speed, we found an acceleration equal to:
 

In order to have this acceleration, there must be a force (or combination of forces) that provides this acceleration. 
 
 
 

• Draw a vector indicating the direction of the acceleration of the car.
• Draw a free-body diagram for the car. 
• If m= 100 kg, v= 10 m/s and r= 20 m find:
• The magnitude of the carís acceleration.
• The magnitude of the net force acting on the car
• The magnitudes of all of the forces in your free-body diagram.
