Masses 18 kg and 9 kg are connected by a light string that passes over a frictionless pulley as shown in the figure.
The acceleration of gravity is 9.8 m/s2 . 18 kg
9 kg
If the 18 kg mass, initially held at rest on the table, is released and moves 1.7 m in 1.4 s, determine the coefficient of kinetic friction between it and the table.
