A bicyclist starts at 2.5 m/s and accelerates along a straight path to a speed of 12.5 m/s in a time of 4.5 seconds. What is the bicyclist's acceleration to the nearest tenth of a m/s??

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.
