A lead shot of diameter 3 mm is fired upward into still air at 300 K over open water. Calculate:

a) The drag force on the shot as it leaves the gun barrel at a velocity of 150 m/s

b) The terminal velocity that it attains when it falls through the still air

c) The terminal velocity that it attains when it falls through the still water.

Apply the K-test.

Data:

rho Pb = 11,340 kg/m3
rho air = 1.177 kg/m3, eta air = 1.85 A????1 10?5 Pa-s

rho H2O = 997 kg/m3, eta H2O = 8.57 A????1 10?4 Pa-s
