15\,\text{kg}

sled is pulled along a horizontal snowy surface by a rope that exerts a constant

60\,\text{N}

force parallel to the motion. The coefficient of kinetic friction between sled and snow is

0.15

. The sled’s initial speed is

2.0\,\text{m}\!\cdot\!\text{s}^{-1}

, and it is pulled for

25\,\text{m}

. Using

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

, determine the sled’s speed after being pulled the

25\,\text{m}
