Homework Statement
A mass on a horizontal friction-free air track is accelerated by a string attached to another 10kg mass hanging vertically from a pulley. Suppose the masses described are 1kg and 100kg. Compare the acellerations when the masses are interchanged, that is, for the case when the 1kg mass dangles over the pulley and then the case where the 100kg mass dangles over the pulley. What does this indicate about the maximum acceleration of such a system of masses?
Homework Equations
Fg=mg
a=f/m
The Attempt at a Solution
I found the two acellerations (.099m/s^2 and 9.9m/s^2 respectively). However I do not understand what they mean by maximum acceleration or what the two acellerations indicate.
