Question 7: An astronaut is drifting away from the space shuttle at a velocity of 1.1 m/s.
Luckily he has his gun with him and he decides to fire his
gun's 30 g bullets as a means of returning to his ship. The mass of the astronaut
and his spacesuit is 123 kg, his gun has a mass of 12 kg and the bullets leave his
gun at 250 m/s.

b) What is the approximate minimum number of bullets that he will need to fire to begin drifting
back to the ship?

None of the choices is a suitable fill-in for the blank.

The question is fishing for "solution", but that makes
the statement false and misleading.

Salad dressing is a well-blended mixture. 
Blood is a well-blended mixture. 
Milk is a well-blended mixture. 
Petroleum is a well-blended mixture. 
None of these substances is a solution. 
A solution is not a well-blended mixture.
