An iceboat is at rest on a frictionless frozen lake when a sudden wind exerts a constant force of 220 N, toward east, on the boat. due to the angle of the sail, the wind causes the boat to slide in a staraight line for a distance of 8.5 m in a direction 20° north of east. What is the kinetic energy of the iceboat at the end of that 8.5 m?
