A hockey puck of mass 1 kg is traveling at 2 m/s in a direction 40º south of east. It collides with a stationary puck of mass 0.9 kg. After the collision, the 1 kg puck is traveling at an angle of 60º south of west at a speed of 0.8 m/s. What is the speed and direction of the 0.9 kg puck?

A 5.991E-3 kg pellet is fired at a speed of 71.29 m/s at a motionless 0.4229 kg piece of wood. When the pellet hits the wood, it sticks in the wood, and they slide off together. With what velocity to they slide?

Two football players collide head-on in midair while chasing a pass. The first player has a 100.5 kg mass and an initial velocity of 4.20 m/s, while the second player has a 122 kg mass and initial velocity of -3.9 m/s. What is their velocity (in m/s) just after impact if they cling together? (Indicate the direction with the sign of your answer.) m/s

An Astornaht floating at rest in space has run out of fuel in her jet pack. She realizes that throwing tools from her toolkit in the opppisye direction will help her propel backwards towards her space station. If the astronaut has a mass of 80 kg am she throws a hammer of a mass 4.5 kg at a speed of 4 m/a what will be the appropriate resultant velocity that carries her back to the space station.

Two football players collide head-on in midair while chasing a pass. The first player has a 95.0 kg mass and an initial velocity of 5.60 m/s, while the second player has a 114 kg mass and initial velocity of -3.7 m/s. What is their velocity (in m/s) just after impact if they cling together? (Indicate the direction with the sign of your answer.) m/s?

What is the velocity (in m/s) of a 905 kg car initially moving at 25.0 m/s, just after it hits a 125 kg deer initially running at 12.5 m/s in the same direction? Assume the deer remains on the car. (Enter the magnitude.)

Karen, an aspiring figure skater, collides with bob, a rival figure skater, who had an initial velocity of 3.5 m/s [E]. Karen, who has a mass of 59 kg, had a final velocity of 4 m/s [12o S of E]. Bob, who has a mass of 55 kg, had a final velocity of 3.7 m/s [56o N of W]. What was the initial velocity of Karen?

Question #2 and #3. Thanks!

A 9.97 kg red car traveling 7.71 m/s to the right collides with a 17.33 kg blue car traveling 7.19 m/s to the left.  What is the velocity of the two cars after the inelastic collision?  Round your answer to 2 decimal places.

a 21.4 g object moving to the right at30.5 cm/s overtakes and collides elasticallywith an 8.74 g object moving in the samedirection at 26.7 cm/s.Find the velocity of the 21.4 g object afterthe collision.
