Robin would like to shoot an orange in a tree with his bow and arrow. The orange is hanging yf = 5.00 m above the ground. On his first try, Robin looses the arrow at v0 = 36.0 m / s at an angle of θ = 30.0 ° above the horizontal. The arrow has an initial height of y0 = 1.50 m, and its tip is x = 52.0 m away from the target orange. Treating the arrow as a point projectile and neglecting air resistance, what is the height of the arrow once it has reached the horizontal position x of the orange? Use g = 9.81 m / s 2 for the acceleration due to gravity.
