10\,\text{kg}

crate is pulled along a horizontal floor by a light rope that makes an angle of

37^{\circ}

with the horizontal. The tension in the rope is

80\,\text{N}

and the coefficient of kinetic friction between the crate and the floor is

0.25

. If the crate starts from rest, what is its speed after moving

6\,\text{m}

? (a)

9.8\,\text{m\,s}^{-1}

(b)

6.9\,\text{m\,s}^{-1}

(c)

7.9\,\text{m\,s}^{-1}

(d)

5.3\,\text{m\,s}^{-1}
