You and your fellow astronaut are floating in space right next to each other initially at rest. You have a mass of 68 kg and your friend has a mass of 87 kg. You get into an altercation and your friend pushes you. After the push you are traveling at 2.5 m/s in the +x direction. What is your fellow astronauts velocity after the push? Express your answer in meters per second and round to one decimal place.

An astronaut is floating in outer space. There are no external forces acting on the astronaut. The mass of the astronaut plus his/her equipment is 60 kg. The astronaut is at rest with a wrench in their hands. The astronaut then throws the wrench that weights 1 kg at 20 m s-1. The mass of the astronaut is now 59 kg. What is the magnitude of the astronaut's velocity after he/she threw the wrench?

A 71 kg astronaut floating in space simultaneously tosses away a 18 kg oxygen tank and a 6.4 kg camera. The tank moves in the xxx direction at 1.1 m/s , and the astronaut recoils at 0.63 m/s in a direction 200 degrees counterclockwise from the x axis. Find the x-component of the velocity of the camera. Express your answer in meters per second. Find the y-component of the velocity of the camera.\Express your answer in meters per second.

If you are an astronaut floating untethered in space (like Sandra Bullock in the movie "Gravity") and you want to move somewhere, one thing you can do is to throw something in the opposite direction. If you (mass = 80 kg) are at rest but want to start moving at 2 m/s to the right, at what speed would you need to throw a 5-kg box to the left in order to accomplish this? [Note: 80 kg is just you,...

An unfortunate astronaut loses his grip during a spacewalk and finds himself floating away from the space station, carrying only a rope and a bag of tools. First he tries to throw a rope to his fellow astronaut, but the rope is too short. In a last ditch effort, the astronaut throws his bag of tools in the direction of his motion (away from the space station). The astronaut has a mass of 102 kg and the bag of tools...

An astronaut is working outside of the International Space Station when her propulsion system stops working. She's floating in space, not moving relative to space station. Rather than have the rest of the crew break out the robotic arm to pick her up, she decides to use the tools at hand. The astronaut has a gun used for equipment repair that shoots metal pieces at a high speed. The mass of the astronaut and all her equipment is Ma. This...

10. An astronaut drops her space-hammer on Mars where gMars = 3.71 m/s. The space-hammer has a mass of 2.0 kg and a charge of −300 µC to assist with space nails. An electrical storm (only a science fiction thing as far as I know, but let’s pretend) has created an electric field of 40, 000 N/C pointed 30◦ vertically upwards from due East. The space-hammer starts from rest 1.3 meters above the ground. a) (2 points) In which direction...

Far out in space, a bored astronaut fires an antique gun at a sack of rocks (mass M). The bullet (mass m) bounces around inside the sack a few times, eventually emerging with a reduced, but still high, speed. As the bullet flies off into space, the astronaut remembers with dismay that it was a priceless historical artifact. Fortunately, the astronaut knows the initial speed v0 of the bullet, and that the sack was initially at rest but after being...
