An iceboat is at rest on a frictionless frozen lake when a sudden wind exerts a constant force of 212 N, toward east, on the boat. due to the angle of the sail, the wind causes the boat to slide in a straight line for a distance of 7.0 m in a direction 20° north of east. What is the kinetic energy of the iceboat at the end of that 7.0 m?

Work done on the boat= force*distane*cos20.
Set that equal to KE
