Two iceboats (one of mass m, one of mass 2m) hold a race on a frictionless, horizontal, frozen lake. Both i iceboats start from rest, and the wind exerts the same constant force on both iceboats. Which iceboat crosses the finish line with more kinetic energy (KE)? Start Finish O The iceboat of mass 2m: it has four times as much KE as the other. O The iceboat of mass m: it has four times as much KE as the other.

Question
Two iceboats (one of mass m, one of mass 2m) hold a race on a frictionless, horizontal, frozen lake. Both i iceboats start from
rest, and the wind exerts the same constant force on both iceboats. Which iceboat crosses the finish line with more kinetic
energy (KE)?
2m
Start
Finish
The iceboat of mass 2m: it has four times as much KE as the other.
The iceboat of mass m: it has four times as much KE as the other.
The iceboat of mass 2m: it has twice as much KE as the other.
The iceboat of mass m: it has twice as much KE as the other.
They both cross the finish line with the same kinetic energy.
