A rope attached to a box and is pulled at an angle of 30* above the horizontal with a force of P.

Is the acceleration of this box the same as in this situation when..

A straight bar is pushed up into the back of a block at 30* above the horizontal with the same force P.

I question this because of don't know if the second situation lowers the Normal Force or if it stays the same. Thanks in advance.

**block, no back
