Consider a rectangular foam boat $12$ $cm$ wide by $30.7$ $cm$ long by $4.2$ $cm$ deep. Imagine this boat is loaded with enough cargo so the bottom sits $1.8$ $cm$ below the waterline. Determine the pressure drag force if the boat moves at $0.9$ $m/s$ and the pressure drag coefficient is taken to be $.95$. $F_p=$ $N$
