A construction worker attempts to pull a stake out of the ground by pulling on a rope that is attached to the stake and makes an angle of 60.0° with the horizontal. The worker exerts a force of 125 N on
the rope. What is the magnitude of the upward component of the force acting on the stake?

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.
