A50 kg boy runs and jumps with a forward velocity of 1.5 m/s into a 125 kg stationary boat.
what is the final velocity of the boy/boat system?
a. 0.43 m/s, forward
b. 0.43 m/s, backward
c. 1.1 m/s, forward
d. 1.1 m/s, backward

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.
