B. 10,400 N D. 399 N. C___ 2. If a car is moving to the left with constant velocity, one can conclude that. A. there must be no forces applied to the car. B. the net force applied to the car is directed to the left. C. the net force applied to the car is zero. D. there is exactly one force applied to the car. A___ 3.
Acceleration is a vector, and needn't point in the same direction as the velocity vector. As you make a right turn, the bob swings outward, to your left. That means the car's acceleration vector is to your right, perpendicular to your velocity vector.
