A 65kg astronaut (including spacesuit and equipment), is floating at rest a distance of 15m from the spaceship when she runs out of oxygen and fuel to power her back to the spaceship. She removes her oxygen tank (3.0 kg) and flings it away from the ship at a speed of 15 m/s relative to the ship.At what speed relative to the ship does she recoil toward the spaceship? How long must she hold her breath before reaching the ship?

A 61kg astronaut (including spacesuit and equipment), is floating at rest a distance of 10 m from the spaceship when she runs out of oxygen and fuel to power her back to the spaceship. She removes her oxygen tank (3.0 kg) and flings it away from the ship at a speed of 15 m/s relative to the ship. PART A: At what speed relative to the ship does she recoil toward the spaceship? My attempt: m1V1=m2V2 (3kg)(15m/s) = (61kg)(V2) 45...

While on an interplanetary mission, a 58.5-kg astronaut is floating toward the front of her ship at 0.15 m/s, relative to the ship. She wishes to stop moving, relative to the ship. She decides to throw away the 2.50-kg book she's carrying. What should the approximate speed and direction of the book be to achieve her goal?

A 70 kg astronaut floating in space in a 102 kg MMU (manned maneuvering unit) experiences an acceleration of 0.034 m/s when he fires one of the MMU's thrusters For related problem-solving tips and strategies, you may want to view a Video Tutor Solution of Launch of a rocket. Part A If the speed of the escaping N2 gas relative to the astronaut is 450 m/s, how much gas is used by the thruster in 5.0 s? Express your answer...

Review Constants 1 Periodic Part A A spaceship of mass 2.0x10 kg is cruising at a speed of 4.1x10 m/s when the antimatter reactor fails, blowing the ship into three pieces. The first piece, having a mass of 5.0x10kgis blown straight backward with a speed of 2.1x10 m/s. A second piece, with mass 8.5x10 kg. continues forward at 1.1x10 m/s What is the speed of the third piece? Express your answer using three significant figures and include the appropriate units....

Having successfully boarded the cargo vessel, Defiance Drake removes her emergency spacesuit, complete with its 10.0 kg atmospheric bottle. Surprisingly, she encounters no human crewmembers, but finds that the ship is host to at least one Enyaki warrior (mission: destroy all humans). She and the alien float weightless in the freighter, at rest with respect to each other. Defiance decides to whip her air canister at the alien and flee. She exerts a constant force of 240. N on the...

An astronaut in her space suit has a total mass of m, = 90.0 kg, including suit and oxygen tank. Her tether line loses its attachment to her spacecraft while she's on a spacewalk. Initially at rest with respect to her spacecraft, she throws her oxygen tank of mass m, - 12.0 kg away from her spacecraft with a speed v = 7.50 m/s to propel herself back toward it (see figure). (a) Determine the maximum distance she can be...

A Review Constants Periodic Table Part A A car with a total mass of 1500 kg (including passengers) is driving down a washboard road with bumps spaced 6.0 m apart. The ride is roughest- that is, the car bounces up and down with the maximum amplitude-when the car is traveling at 6.4 m/s For the steps and strategies involved in solving a similar problem, you may view a Video Tutor Solution What is the spring constant of the car's springs?...
