Aspy is running across the bridge of an aircraft carrier. the spy is moving with a velocity of - 4 m/s relative to the carrier. however, the aircraft carrier is moving with a velocity of 12 m/s. there is a person standing stationary on a beach watching the event. what will be the velocity of the spy according to the person on the beach? 8 m/s 6 m/s -4 m/s -7 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.
