Construct Your Own Problem
Consider an astronaut in deep space cut free from her space ship and needing to get back to it. The astronaut has a few packages that she can throw away to move herself toward the ship. Construct a problem in which you calculate the time it takes her to get back by throwing all the packages at one time compared to throwing them one at a time. Among the things to be considered are the masses involved, the force she can exert on the packages through some distance, and the distance to the ship.

ANSWER:
Problem 63 PE
Step 1 of 6
An astronaut in deep space cut free from her spaceship is at a distance of 20.0 m .She is carrying two packages of mass 5 kg each with her. The mass of the astronaut with the packages is 70 kg.
The astronaut throws the packages with a velocity of 5.00 m/s to move herself towards the ship. (By neglecting,the gravitational force between her and the packages) .
Calculate the time it takes her to get back to the ship by a) throwing all the packages at one time. b.) throwing one package at a time.
a.)
