When the effect of aerodynamic drag is included, the y-acceleration of a baseball moving vertically upward is au = -g - kv², while the acceleration when the ball is moving downward is ad = -g + kv², where k is a positive constant and v is the speed in meters per second. If the ball is thrown upward at 30 m/sec from essentially ground level, compute its maximum height h and its speed vf (a positive number) upon impact with the ground.
