1. The problem statement, all variables and given/known data As shown in the attachment. At the instant shown the block is moving down the slope. What is the acceleration of the block up the slope if the kinetic coefficient of friction is 0.4? 3. The attempt at a solution I'm having problems with two things here, the calculation of the normal reaction on the block as i dont know what to do about the angle of the line on the pulley and its resultant force... This leads to my second problem when summing the total force in the x-direction i still dont know what to do with the 47N force.... Generally i need help!
