You are standing on a sheet of ice that covers the football stadium parking lot in Buffalo; there is negligible friction between your feet and the  ice. A friend throws you a 0.700-kg ball that is traveling horizontally at 10.0 m/s. Your mass is 20.0 kg. If you  catch  the  ball,  with  what speed do you and  the  ball  move afterward?

Your mass is 63.2 kg, and the sled s mass is 21.7 kg. You start at rest, and then you jump off the sled, after which the empty sled is traveling at a speed of 4.27 m/s. What will be your speed on the ice after jumping off?     1.47 m/s     0.88 m/s     2.06 m/s     1.77 m/s

2. In a scifi movie about astronauts on a space station, one of the astronaut's safety line is cut while on a space walk. The astronaut, who 10 meters from the shuttle and is moving 0.1 m/s away from it, finds that the suit's thruster pack has also been damaged and no longer works and that only 30 seconds of air remains. To get back to the shuttle, the astronaut unstraps a 10-kg tool kit and throws it away with a speed of 5 m/s. In the scene, the astronaut, who has a mass of 100 kg without the toolkit, survives. Is this reasonable?

A loaded gun is dropped on a frozen lake. The gun fires, with the bullet going horizontally in one direction and the gun sliding on the ice in the other direction. The bullet's mass is 0.03 kg, and its speed is 280 m/s. If the gun's mass is 1.8 kg, what is its speed (in m/s)?

A baseball with a mass of 0.15 kg is batted into the air. It's initial speed is 35.8 m/s directed at an angle 28 degrees above the horizontal. After 0.19 seconds what is the horizontal component of the balls velocity in m/s?

A loaded gun is dropped on a frozen lake. The gun fires, with the bullet going horizontally in one direction and the gun sliding on the ice in the other direction. The bullet's mass is 0.03 kg, and its speed is 295 m/s. If the gun's mass is 2.5 kg, what is its speed (in m/s)?  m/s

Your mass is 92.6 kg, and the sled s mass is 17.1 kg. You start at rest, and then you jump off the sled, after which the empty sled is traveling at a speed of 3.11 m/s. What will be your speed on the ice after jumping off? 0.57 m/s 0.46 m/s 1.03 m/s 0.80 m/s
