The equation for the speed (not the height) of a ball that is thrown straight up in the air is given by v = 128 – 32t, where v is the velocity (in feet per second) and tis the number of seconds after the ball is thrown. With what initial velocity was the ball thrown? What is the meaning of the slope?
