3.0\,\text{kg}

block rests on a horizontal surface where the coefficient of static friction is

0.25

. The block is attached by a light string that passes over an ideal pulley to a hanging mass

m_h

. The system remains at rest. Determine the value (or range of values) of

m_h

that satisfies this equilibrium condition.
