A moose pulls a 172-kg sled across a flat surface. The moose is connected to the sled by a rope that is angled 28.5 degrees from the horizontal direction, and the moose creates a constant tension of 681 N in the rope. Assume that friction between the sled and the ground is negligible. If the moose and sled start out motionless and the moose pulls the sled 26 meters across the ground, what is the final speed of the sled? Answer in m/s, giving the number only, without the units
