$(10\%)$ A sphere having a diameter of $0\mathrm{.}7m$ is tethered $5m$ below the still water level where the water depth is $10m.$ A $6s,1m$ high wave passes the sphere. Determine and plot the horizontal components of the drag, inertia, and total force on the sphere through one wave period. Assume $C_d=0\mathrm{.}6$ and $C_m=1\mathrm{.}5.$
