(a) Objects with masses m, - 16.0 kg and m, - 9.0 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, m, falls 1.00 m in 1.23 s, determine the coefficient of kinetic friction between m, and the table. (b) What If? What would the minimum value of the coefficient of static friction need to be for the system not to move when released from rest?

(a)
Objects with masses m,
= 16.0 kg and m2
= 9.0 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, m,
1.00 m in 1.23 s, determine the coefficient of kinetic friction between m, and the table.
(b) What If? What would the minimum value of the coefficient of static friction need to be for the system not to move when released from rest?
