Problem

A sled is being towed across level snow at a constant speed of

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

. The tow rope makes an angle of

25^{\circ}

above the horizontal, and the person pulling supplies a constant power output of

350\,\text{W}

. Assume air resistance is negligible and that the sled’s speed remains constant. (a) Calculate the magnitude of the force exerted through the rope.
