In the event of an emergency, a nuclear reactor is shut
down by dropping the control rod R, having a weight of
20 lb, into the reactor core C, as shown in (Figure 1).
A
If the rod is immersed in "heavy" water, which offers a drag resistance to downward motion of FD = (0.25v) lb, where v
is the velocity of the rod in ft/s, determine the distance s it must descend into the reactor core when it attains a speed of
14 ft/s. The rod is released from rest when s = 0. Neglect the effects of buoyancy.
Express your answer in feet to three significant figures.
