Homework Help: physics

Posted by james on Sunday, November 10, 2013 at 4:43pm.

Masses 19 kg and 9 kg are connected by a light string that passes over a frictionless pulley as shown in the figure ( The figure shows the 19 kg block on the table connected by a string through a pulley which is connected to the 5 kg block hanging off the table). The acceleration due to gravity is 9.8m/s. If the 19 kg mass, initially held at rest on the table, is released and moves 1.2 m in 1.4s, determine the coefficient of kinetic friction between it and the table.
