If the distance between each vertical tick mark represents 2 m, what is the average speed
of car Y and car Z for the time interval t = 0 to t = 6 s?
Average speed for Y is 9 m/s and average speed for Z is 8 m/s.
Average speed for Y and Z is 10 m/s.
Average speed for Y is 54 m/s and average speed for Z is 56 m/s.
Average speed for Y is 0.11 m/s and average speed for Z is 0.125 m/s.
The acceleration of the cars are related as follows:
Acceleration of Y > acceleration of Z.
Acceleration of Y = acceleration of Z > 0.
Acceleration of Z > acceleration of Y.
Acceleration of Y = acceleration of Z = 0.
If you were a passenger in car M, how would you describe the motion of car L?
Car L would look like its moving forward at a constant speed.
Car L would look like its moving backward at a constant speed.
Car L would initially look like its moving forward and after 1 second look like its moving backward.
Car L would look like its not moving at all.
Are the cars ever at the same position at the same time?
No.
Yes, at instant 1.
Yes, at 1 and 4 for car L and at 1 and 3 for car M.
Yes, at 4 and 7 for car L and at 3 and 5 for car M.
The acceleration of the cars are related as follows:
Acceleration of L > acceleration of M.
Acceleration of L = acceleration of M > 0.
Acceleration of M > acceleration of L.
Acceleration of L = acceleration of M = 0.

During what time interval(s) is the object moving at constant velocity?
During t = 0 to t = 12 s.
During t = 12 s to t = 20 s.
During t = 20 s to t = 28 s.
During t = 28 s to t = 40 s.
Both A and C are correct.
