QUESTION:

Falling Object. The motion of an object moving vertically through the air is governed by the equation where y is the upward vertical displacement and V is a constant called the terminal speed. Take g = 32 ft /sec2 and V = 50 ft/sec. Sketch trajectories in the yv-phase plane for starting from y = 0 and v =-75,-50, -25, 0, 25, 50, and 75 ft/sec. Interpret the trajectories physically; why is V called the terminal speed?
