An astronaut is floating inside the international space station at rest--and since there are no other external forces she can rely on to change her state of motion--she decides to throw her jacket across the room. If her mass is 66.9kg and she throws the 1.1kg jacket at 14.7 m/s -- what is her recoil speed?

Solutions

Expert Solution

Given:

Mass of the astronaut,

Mass of the jacket,

Final velocity of the jacket,

-----------------

Initially, both the astronaut and the jacket are at rest

While throwing the jacket, momentum is conserved

Initial momentum = Final momentum

Negative sign just indicates that the astronaut will be moving in a direction opposite to the direction of jacket.

A 50 kg Astronaut is floating in space, at rest relative to her spaceship. The 5kg canister she used for getting around has run out of gas. To get back to the spaceship she decides to throw the canister in the opposite direction. a) What is the total momentum of the astronaut-canister system after the throw (relative to the spaceship)? b) If the canister moves away at a speed of 20 m/s, what is the Astronaut’s speed toward the spaceship?

Is there gravity in space? Explain why? If an astronaut leaves his air-filled space station and takes his guitar out into space on a spacewalk, another astronaut will not be able to hear the sound guitar as he plays it. Why? Moon's radius distance from the centre of the Earth is given by ‘R’. If this radius is increased to 1.5 times ‘R’, how would this change affect the magnitude of gravitational force of the Earth on the Moon? How...

Your spaceship has docked at a space station above Mars. The temperature inside the space station is a carefully controlled 24 ∘C at a pressure of 735 mmHg . A balloon with a volume of 515 mL drifts into the airlock where the temperature is -83 ∘C and the pressure is 0.120 atm . What is the final volume, in milliliters, of the balloon if n remains constant and the balloon is very elastic?

The International Space Station uses the electrolysis of water to continuously replenish the oxygen in the station’s atmosphere (the hydrogen formed is vented). The station’s electricity is generated by the four arrays of solar modules, which produce a total of 120 kW. Essential heating/cooling, circulation and steering equipment requires 75 kW. If one of the four modules fails completely, this leaves 15 kW for O2 production, which is run at a 2 V potential. How many astronomers can survive on...
