In procedure 2, you found the coefficient of kinetic friction by measuring the acceleration of a cart under the influence of the combined forces of friction, normal force, gravity, and tension in string from which masses were hanging. Suppose you add more masses to the hanging weight, therefore increasing the tension and hence the acceleration for this system to double (2 x) its original value. How many times of the old value of the coefficient of kinetic friction will the new value be?
