Question
Objects with masses m1 = 14.0 kg and m2 = 6.0 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 1.47 s, determine the coefficient of kinetic friction between m1 and the table. 1 Incorrect: Your answer is incorrect. Express the friction force in terms of the coefficient of kinetic friction. Obtain an expression for the acceleration in terms of the masses and the net force, including friction, and solve for the coefficient of kinetic friction.
Explanation / Answer
Objects with masses m1 = 14.0 kg and m2 = 6.0 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 1.47 s, determine the coefficient of kinetic friction between m1 and the table.
Net force = total mass * acceleration
The weight of the 14 kg object causes both objects to accelerate. The friction force causes both objects to decelerate.
Net force = (6.0 * 9.8)
