Question: A smooth steel ball 1-cm in diameter (W 0.04 N) is fired vertically at sea level at an initial velocity of 1000 m/s. Its drag

A smooth steel ball 1-cm in diameter (W ≈ 0.04 N) is fired vertically at sea level at an initial velocity of 1000 m/s. Its drag coefficient is given by Fig. 7.20. Assuming a constant speed of sound (343 m/s), compute the maximum altitude attained (a) by a simple analytical estimate; and (b) by a computer program.
