Berry places a ball at the edge of the hill (the origin of the coordinate system), and kicks the ball at a speed of 20 m/s and at an angle of 30o to the horizontal. The equation describing the ballís height as a function of the horizontal distance it travels is given by . How far down the hill does the ball land?
