Homework Statement

Calculate the acceleration for a 10.0kg block which is being pulled up a 35 degree slope by a force of 140 N if the coefficient of friction is 0.100 The answer is to be in m/s2

Homework Equations

Ff=UN

The Attempt at a Solution

I am having trouble getting started and putting the parts of the problem together.

Start with a picture and free-body diagram.

I have a free body which a 140 N force going along the + x-axis a N force (normal) going + along Y axis a vector "W" in the third quad with a polar angle of 235'. What do i do next. I know that i need to find the acceleration of the block. Where and how does the coeficient of friction come into play here?

 

[ehild]

I still need that picture with all forces shown. There is gravity and friction in addition to that 140 N force. The resultant force accelerates the block.
