Problem

5\,\text{kg}

block rests on a horizontal table. The coefficient of static friction between the block and the table is

\mu_s = 0.30

. The block is connected by a light string over a smooth pulley to a hanging mass

m

. Taking

g = 9.8\,\text{m\,s}^{-2}

, determine the least value of

m

that will just start the motion of the system.
