Bob releases a toy car at the top of the derby car ramp. predict the motion of the car at 6 seconds.

a) the race car decelerates as it approachs in the bottom of the ramp.

b) the car continues at a constant rate in a linear path down the ramp.

c) the derby race circuit will end before 6 seconds so the car will stop.

d) the derby car continues to accelerate as it travels in a straight line.

Which object is most likely represented by a dot?

Am i correct on these two physics questions?

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.
