the next two questions refire to the following scenario. An archer, whose arrow is known to leave his bow at a velocity of 60.0 m/s is challenged to shoot an apple launched vertically at 20.0m/s a distance 75 m away. Both the arrow and the aple are launched from the same altitude at the same time.
A) Determine the horizontal velocity of the arrow
B) At what altitude (height above the launch point of the apple) does the arrow hit the apple?
