Problem
A ball is thrown from level ground with an initial speed of 20m⋅s−1 and is required to land on level ground 30m away. Neglect air resistance. Which of the following statements about the launch angle(s) relative to the horizontal is most accurate?
(a) Exactly one angle of about 24∘ will allow the ball to reach the target distance.
(b) Two distinct angles, one less than 45∘ and one greater than 45∘, will allow the ball to reach the target distance.
(c) Exactly one angle of about 45∘ will allow the ball to reach the target distance.
(d) No launch angle will allow the ball to reach the target distance because the speed is insufficient.
