Frictionless plane at angle of theta=69degrees

[mrshappy0]

Homework Statement

A table is tilted at an angle of θ = 69° with respect to the vertical. Find the magnitude of the new acceleration of block 1. Mass of the block 1 which is on the incline of the plan is 6. Mass of block 2 which is hanging freely from the pulley is 3.9.

Homework Equations

F=ma

The Attempt at a Solution

I drew the free body diagram and started working on block one and set the x-axis parallel to the plane and have the y-axis perpendicular to make it easier. Fnet,alongx=T-Wtan(theta)=m1(a). Then I went on to work on Fnet,alongy=.. and it started looking really complicated. Not sure if I am approaching it correctly.

I am struggling to grasp the problem definition. I can understand that there is a table, which makes an angle of $69^{\circ}$ with the vertical. It initially as a block M_{1} on the table at rest, and you wish to know the net acceleration. I do not understand your reference to a pulley and block 2, where is the pulley?

Could you also expand on what T and W are?

From what I can see you should have 2 forces acting on the mass, M1. So for your Fnet_along y there should be a maximum of two terms?

Thanks
