Posted by mike on Tuesday, February 19, 2013 at 5:53pm.

Masses 15 kg and 8 kg are connected by a light string that passes over a friction-less pulley with the 15 kg mass on a table and the 8 kg mass hanging off the edge.
The acceleration of gravity is 9.8 m/s2.

If the 15 kg mass, initially held at rest on the table, is released and moves 1.5 m in 1.5 s, determine the coefficient of kinetic friction
between it and the table.
