An archer stands a horizontal distance d= 55 m away from a tree sees an apple hanging from the tree at h= 12 m above the ground. The archer chooses an arrow and prepares to shoot. The arrow is initially 1.5 m above the ground. Just as the archer shoots the arrow with a speed of 80 m/s , the apple breaks off and falls straight down. A person of height 2.0 m is standing directly underneath the apple. The arrow pierced the apple. Ignore air resistance, and use g=9.81 m/s2 for the acceleration of gravity.
(a) What angle did the archer aim the arrow? enter your answer in degrees
(b) How high above the person's head did the arrow hit the apple?
