Attempt at a solution is not just 17... haha... Show your equations that you used, so we can help you... Did you draw your FBD's for the 2 masses?

 

[WillemBouwer]

Very easy once you have done the equations for both the masses...

This is a very straight forward problem.

Newton's Second Law!

If you draw a free body diagram of each block you will have:

ƩF_BLOCK1=ma

F_PULL - T = ma

ƩF_BLOCK2=ma

T = ma

----

You are given that the masses are equal to each other and the system will accelerate at the same rate!

Yes Bill Nye Tho, for you it is very easy, but the purpose of this forum is to help people understand what they deal with by letting them do the problem themself, we just aid them when they struggle... Try helping not just showing that you know the answer...
