Can someone help me with this Physics Question?

If you're saying up is positive then left is positive for the horizontal plane. I don't feel like doing the math because I'm without a pencil and paper however, I'll tell you how to solve this. Draw two free body diagrams of the twos mes. The first m will have the normal force, force of gravity and the force of tension acting on it. Since it's inclined, you will have to find the components of the gravity vector using 32.9 degrees as the contained angle and (6.27)(9.8) as the magnitude of the gravity vector. Use sin and cos to find the magnitudes of the force of gravity in the horizontal plane and vertical plane. Since the block is not moving up or down, its normal force and its vertical component of gravity will cancel out and you're left with the horizontal component and the tension force. There can be only one tension in a rope so both mes must have the same acceleration. Now use the appropriate equation and solve, if you have further questions or can't solve it, then I'll actually do it, just email me if you have any problems
