A velocity-time graph is shown below: (2 points) What is the average acceleration of the object represented in the graph above over the 10 seconds?
0 m/s2
2 m/s2
4 m/s2
6 m/s2

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
