Question #22832

USE conservation of momentum for-

mula. The astronaut will have the same mo-

mentum as the oxygen tank - only in the

reverse direction. ——

A 62.5 kg astronaut is on a space walk when

the tether line to the shuttle breaks. The

astronaut is able to throw a 11.0 kg oxygen

tank in a direction away from the shuttle with

a speed of 11.4 m/s, propelling the astronaut

back to the shuttle.

Assuming that the astronaut starts from

rest, find the final speed of the astronaut after

throwing the tank.

Answer in units of m/s

Answer in units of m/s

Expert's answer

The equation for theconservation of momentum:

62.5 kg * (-v) + 11.0 kg * 11.4 m/s = 0;

v = 11.0 kg * 11.4 m/s / 62.5 kg = 2.006 m/s

Answer: 2.006 m/s

62.5 kg * (-v) + 11.0 kg * 11.4 m/s = 0;

v = 11.0 kg * 11.4 m/s / 62.5 kg = 2.006 m/s

Answer: 2.006 m/s
