Aforce of 20. newtons to the left exerted on a cart for 10. seconds. for what period of time must a 50.-newton force to the right act to produce an impulse of equal magnitude on the cart?

What does the law of conservation of mass state?

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.

You can melt ice by applying pressure because the solid/liquid line has a slope.
