A car is moving to the left at a speed of 90 miles per hour. Another car is moving to the right at a speed of 90 miles per hour. Compare the speed and velocity of the two cars.
The cars have the same velocity and speed.
The cars have the same speed, but different velocities.
We cannot say anything about the velocities of the two cars.
There is not enough information to make a comparison.

The following describes the motion of a car. From 0 to 3 seconds, the car speeds up, moving away from the motion sensor. From 3 to 6 seconds, the car slows to a stop, before speeding up toward the motion sensor from 6 to 9 seconds. From 9 seconds onward, the car travels at a constant speed toward the motion sensor. Which velocity-time graph best depicts the situation?
Graph A
Graph B
Graph C
Graph D
