the force acting required to tow a boat at constant velocity is directky proportional to speed...if a speed 4 km/hr,corresponding power is 7.5kw....how much power is neede for speed=12km/hr?
Dear shivanshi
given
F= α V
power P = FV
=α V2
7.5 =α * 16
α =7.5/16
so at 12 km/hr
P = α * 144
=7.5/16 * 144
=67.5 kw
