4.0\,\text{kg}

block rests on a horizontal surface where the coefficient of static friction is 0.50. It is connected over a frictionless pulley to a hanging

1.8\,\text{kg}

mass. The system is released from rest. Will the

4.0\,\text{kg}

block remain at rest or will it start moving? Briefly explain your reasoning.
