An object falls at a rate of \(100 \mathrm{ft} / \mathrm{s}\) immediately prior to the time that the parachute attached to it opens. The final descent rate with the chute open is \(10 \mathrm{ft} / \mathrm{s}\). Calculate and plot the speed of falling as a function of time from when the chute opens. Assume that the chute opens instantly, that the drag coefficient and air density remain constant, and that the flow is quasisteady.
