Problem: You would like to shoot an orange out of a tree with your bow and arrow. The orange is hanging 5.00 m above the ground. On your first try, you fire the arrow at 34.0 m/s at an angle of 30.0° above the horizontal from a height of 1.40 m while standing 44.0 m away. Treating the arrow as a point projectile and neglecting air resistance,
Part A: What is the height of the arrow once it has travelled the 44.0 m horizontally to the tree?
Please show all intermediate steps and formulas for above problem.
