10\,\text{kg}

crate lies on a horizontal floor where the coefficient of static friction is

0.30

. A force is applied through a rope that makes an angle of

30^{\circ}

above the horizontal. Calculate the minimum magnitude of the force needed to just start moving the crate. \,(Take

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