An iceboat of mass M = 250 kg sits motionless on a frozen lake. A steady wind starts to blow from the West, pushing the boat with a constant force F = 150 N. The boat slides without friction at theta = 23 degrees North of East, a distance D = 100 m.

How fast is the boat moving when it reaches the point marked "X"?
