I think I kinda see it now. Thanks!

I got it right by taking 958-(small mass)(g)=(small mass)(a). I got a=12.99 m/s^2. So, my homework is now done, but even though I figured out the right number, I'm still conceptually having a problem seeing the difference between Case A and Case B.

I'm betting it's not... But I don't know how to calculate it.

I don't know. It's the opposite of gravity? I know that doesn't work since there's acceleration other than gravity acting in the downward direction, but I don't know how to solve for tension when there are so many variables you don't know.

I found something in my book that says that a the force T applied at one end of amassless rope is transmitted undiminished to the other end. Does this mean that T=958 N on both sides?

I'm still lost. The mass of the hand is probably different from the mass of the block, but as long as the force is the same, I don't see how it would change anything.
