The angular acceleration of an object as a function of time is given by the equation: alpha open parentheses t close parentheses equals open parentheses 2 rad over straight s cubed close parentheses t minus open parentheses 6 rad over straight s to the power of 4 close parentheses t squared what is the change in the angular velocity of the object (in rad/s) from t = 0 s to t = 2 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.
