Here's one from my HW: Two blocks are connected by a massless string on a triangle with a pulley at the top corner. The angle of the left corner is 35 degrees. the angle on the right is 60 degrees. the left block equals 7kg and the right is 9 kg. mu k = 0.25 Determine acceleration of block A and B Will the tension exceed 70 N? What is the magnitude and direction of frictional force on A? on B?
