William Tell is said to have shot an apple off his son's head with an arrow. If the arrow was shot with an initial speed of 35.0 m/s and the boy was 19.5 m away. (Assume that the arrow and apple are initially at the same height above the ground.)
(a) What is the smaller of the two possible launch angles?
(b) What is the larger of the two possible launch angles?
(c) If Mr. Tell is a good and decent man, which angle is preferable to preserve his son's life? Explain.
