Question

An iceboat with a mass of 30 kg moves on a horizontal lake with a coefficient of friction of 0.5. If the wind exerts a constant force, Fon the iceboat that starts from rest and covers a distance of 25.0 m in 1 minute. What is the velocity of the iceboat at a distance of 25.0 m?​

Answer 1

1.5kJ

Step-by-step explanation:

W=Fd cosϕ=1504 J .
Then, by the work-kinetic energy theorem, we find the kinetic energy

Kf​=Ki​+W=0+1504 J.
