I posted this in the advanced forum by mistake so I'm am posting it here as I think it may be more appropriate in this forum.
A motor boat is speeding at velocity W0 when the motor is turned off and a scoop is lowered into a still lake. The scoop captures flow with a cross section A. If the initial mass of the boat is M0 and the wave and friction drag are negligible, what is the velocity of the boat as a funtion of time?
the momentum equation. I'm not sure how to account for the "scoop" though
I am using the momentum equation but am not sure how to incorporate the effect of the scoop into it.
Any help would be greatly appreciated!
