A 2000-kg airplane flies at 343 m/s. What is its momentum?
A marksman fires a 7.5-g bullet from a loosely held 1.2-kg handgun. The bullet travels away at +365 m/s. At what velocity does the handgun recoil?
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?
Two 500-g carts move on a frictionless air track. Cart A is moving at +0.1 m/s when it collides into Cart Bat rest. The two carts get stuck together. At what velocity will the combined carts move?
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.)
Two skaters, a 70-kg man and a 50-kg woman, are initially at rest on an ice rink and then "push off" from each other and move in opposite directions. After the push-off, the woman moves with a velocity of +2.5 m/s. What is the velocity of the man?
What is the magnitude of the momentum of an electron moving at 90 percent of the speed of light?
Two railroad cars (2 X 10^4 kg each) are traveling in the same direction along a railroad track. Car A is traveling at 14 m/s, and Car B is traveling at 10 m/s. When Car A catches up with Car B, the two cars link together. What is the velocity of
Consider the collision shown to the right. M1 is moving to the right at 12 m/s. M2, that has one-sixth of the mass of M1, is moving to the left at 3.4 m/s. How fast will M2 be moving after the collision? (Assume the table is frictionless)
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?
