An unfortunate astronaut finds himself stranded in space 15.0 meters away from his spacecraft, completely motionless with respect to the spacecraft. Since he cannot walk or swim in space, he recalls some basic physics and decides to take a 0.500 kg tool from his belt and launch it away from the craft, expecting his recoil will move him toward the spacecraft. If the astronaut's mass is 120 kg and he can throw the tool at a speed of 30.0 m/s,...

The Helios spacecraft traveling at a speed of 0.60 c relative to the Earth-Sun system, detects the explosion of a very powerful solar flare at it passes by the Sun on its way to Earth. Sometime later on Earth, the constellation of satellites used to track GPS positions fails. Using the data from the Helios spacecraft as it passes by Earth, scientists calculate that the solar flare happened 7.0 min before the failure of the satellites, according to clocks on...

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...
