Homework Statement


A string can withstand a maximum tension of 200 N. What is the maximum upward acceleration one can impart to a 10 kg mass using this string?


Homework Equations


T=ma
a=F/m


The Attempt at a Solution


so i tried just plugging those variables in that equation and i got 20 m/s^2 i know this is wrong but i cant seem to find the right equation to solve this problem. please help i know its simple

Draw out the free body diagram. There's both gravity and the tension of the string that you need to take into account.

And if you know your net force in the downward direction cannot exceed 200 N, then...

And don't forget to include gravity in your force diagrams.
