Question

Block 1 (10 kg) is pulled by a rope from left to right up a ramp which is inclined 45 degrees from the horizontal. The rope pulls on block 1 with a force of 150 N parallel to the surface of the inclined plane. The coefficient of kinetic friction between the block and the surface equals 0.4. On a sheet of paper, draw the free body diagram for block 1 using the two-subscript notation from class. Assume that the x-axis is parallel to the incline and positive in the direction up the incline. After completing the free body diagram, enter below each force and its x & y-components. FORCES on BLOCK 1 Weight force on block 1 by Earth W1E = i + j N Tension force on block 1 by Rope T1R = i + j N Normal force on block 1 by Surface N1S = i + j N Frictional force on block 1 by Surface f1S = i + j N Tries 0/2 What is the acceleration a of block 1?
