1. The problem statement, all variables and given/known data I need to find the coefficient of friction on a surface. Two weights were given, 0.5672kg and 0.050kg 2. Relevant equations m1a + Mm1g = m2g - m2a 3. The attempt at a solution (0.5672kg)a + M (0.5672)(9.81) = (0.050kg)(9.81) - (0.050kg) a M represents the coefficient of friction. I need to solve for that, I just don't know where to take it from here.
