Question
Objects with masses m1 = 12.0 kg and m2 = 8.0 kg are connected by a light string that passes over a frictionless pulley as in the figure below. If, when the system starts from rest, m2 falls 1.00 m in 1.30 s, determine the coefficient of kinetic friction between m1 and the table.

Objects with masses m1 = 12.0 kg and m2 = 8.0 kg are connected by a light string that passes over a frictionless pulley as in the figure below. If, when the system starts from rest, m2 falls 1.00 m in 1.30 s, determine the coefficient of kinetic friction between m1 and the table.
Net force = total mass * acceleration
The weight of the 12 kg object causes both objects to accelerate. The friction force causes both objects to decelerate.
Net force = (8.0 * 9.8)
