the lower block in the figure is pulled by a rope with an unknown tension force (F0) coefficient of fricton (either static or kinetic ) between the lower block and the surface is (N0).
The coefficient of friction ( either static or kinetic) between the lower block and the upper block is also (N0). The masses of the clocks are mU and mL (mL>mU). the lower block moves to the right with acceleration aL .
1) draw a free-body diagram for each of the block. be sure to label each force by the object on which the force is exerted and object that exerts it.
2) on the diagram above label newton's 3rd law force pairs by placing one x on each force of the pair( if there is more than one pair use xx, xxx, etc.)
3) determine the tension force that the string in the left exerts on the upper.
4) determine the tension force F0 (include only givin quantities and constants
