Astudent wants to determine the impulse delivered to the lab cart when it runs into the wall. the student measures the mass of the cart and the velocity of the cart before it hits the wall. what other measurement is necessary to calculate the impulse delivered to the lab cart? the velocity of the cart after it hits the wall the force exerted on the cart by the wall the time the cart is in contact with the wall the acceleration of the cart before it hits the wall

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.
