An arrow is shot at an angle of θ=45∘ above the horizontal. The arrow hits a tree a horizontal distance D=220m away, at the same height above the ground as it was shot. Use g=9.8m/s2 for the magnitude of the acceleration due to gravity.
1) Find ta, the time that the arrow spends in the air.
Answer numerically in seconds, to two significant figures.
2) Suppose someone drops an apple from a vertical distance of 6.0 meters, directly above the point where the arrow hits the tree.
