Question

A 68.5‐kg astronaut is doing a repair in space on the orbiting space station. She is at rest relative to the space station. She then throws a 2.25‐kg tool away from the space station at 3.20 m/s. With what speed and in what direction will she being to move?

Answer:The velocity of astronaut will be 0.105 m/s in opposite direction of the tool.

Explanation:Given that,

Mass of the Astronaut, m = 68.5 kg

Mass of the the tool, m’ = 2.25 kg

Speed of tool, v’ = -3.2 m/s (direction is sway from space station)

It is required to find the speed of the astronaut. The momentum will remain conserved. So,v is the speed if Astronaut

So, the velocity of astronaut will be 0.105 m/s in opposite direction of the tool.
