Problem

5\,\text{kg}

block rests on a horizontal table (

g = 10\,\text{m/s}^2

). It is pulled by a force

F

that makes an angle of

37^{\circ}

above the horizontal. If the coefficient of static friction between block and table is

\mu_s = 0.30

, the least magnitude of

F

needed to just start the motion of the block is closest to a)
