4. Two cars, A and B, travel in the same direction on a highway. At one moment, car A has
a greater velocity than car B. This means at that moment:
a. Acceleration of car A is greater than that of car B.
b. Acceleration of car A is less than that of car B.
c. Acceleration of both cars are equal.
d. Only the magnitudes of the acceleration of both cars are equal.
e. There is not enough information to draw any conclusions regarding
acceleration.
5. In uniform circular motion, centripetal acceleration vector is always:
a. Parallel to the velocity.
b. Perpendicular to the velocity.
c. In the same direction as the velocity.
d. In the opposite direction from the velocity.
e. Sometimes parallel, sometimes perpendicular to the velocity vector. Angle
changes as the position changes.
