Problem an iceboat is at rest on a frictionless frozen lake, Ask an Expert

Academics

Problem: An iceboat is at rest on a frictionless frozen lake when a sudden wind exerts a constant force of 180 N, toward the 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 9.5 m in a direction 21o north of east.

Part A: What is the kinetic energy of the iceboat at the end of that 9.5 m?

Please show complete calculation for above problem thank you!
