incline01_block1+rope+friction.problem
Block 1 (20 kg) is pulled by a rope from
left to right up a ramp which is inclined
50 degrees from the horizontal. The rope pulls on
block 1 with a force of 300 N parallel to the
surface of the inclined plane. The coefficient of kinetic
friction between the block and the surface equals
0.1.
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.
