1. The problem statement, all variables and given/known data In a friction lab to determine the static and kinetic coefficient of friction, there is a block on a flat slope attached to a string which pulled down by a hanging mass. The lab question is: Why is it important to make sure that the string attached to the block is level? 2. Relevant equations none 3. The attempt at a solution is it bc at that angle, it only has one component x (horizontal component) and thus resulted in the lowest required force to move the mass with that string.
