Title
A stationary curling stone is struck in a glancing collision by a second curling stone of equal mass. If the first stone moves away at a velocity of 0.92m/s [N71degreesW] and the second stone moves away at a velocity of 1.25m/s [N44degreesE], what is the
A 1000-kg cannon fires a 15-kg cannonball. The cannon is mounted on a low-friction carriage that allows it to recoil at -1.5 m/s. What is the speed of the cannonball?
A 1.0-kg ball moving at + 10 m/s strikes a wall and bounces back. The collision is perfectly elastic. What is the balls momentum after the collision? (Assume a frictionless surface.)
A dog of mass 10 kg sits on a skateboard of mass 2 kg that is initially traveling south at 2 m/s. The dog jumps off with a velocity of 1 m/s north rela-tive to the ground. Which of the following is the best estimate of the velocity of the skateboard immed
A 2000-kg airplane flies at 343 m/s. What is its momentum?
A 150-kg halfback is running down the field carrying the ball at a velocity of 5 m/s. A 50-kg linebacker from the opposing team is running at him in the opposite direction. The linebacker hopes to wrap him in a tackle
A 10-kg cart moving to the right at 5 m/s has a head-on collision with a5-kg cart moving to the left at 7 m/s. If the carts stick together, what is the velocity of the combination?
A 750-kg aircraft is flying level at 100 m/s. A tailwind blows for 2 min, and the aircrafts speed increases to 120 m/s. What was the average force of the tailwind?
A bullet has a mass of 50 g, and its momentum is 25 kg.m/s. What is the velocity of the bullet?
What is the magnitude of the momentum of an electron moving at 90 percent of the speed of light?
