... • Place the block on its narrow side with, perhaps, 500 grams stacked on it. Readjust the pulley so that the cord is again parallel to the plane. Find the value of m necessary to cause the block to slide at constant speed. This will be your test to see if the frictional force has any dependence on t ...
