We should use the equation for the moment of flight, but we don"t have actually v0. We can discover v0 from the expression for range as:

v0=Rgsin(2θ)=(220)(9.8)sin<(2)(45°)>

v0 =46.43 m/s

An arrowhead is shot in ~ an edge of θ = 45° over the horizontal. The arrow hits a tree a horizontal distance D = 220m away, at the same height over the ground as it was shot. The elevation from i beg your pardon the arrowhead is shooting is 6 m. Use g=9.8m/s2 because that the size of the acceleration due to gravity.

You are watching: An arrow is shot at an angle of θ=45∘ above the horizontal

Part A

Find ta, the moment that the arrow spends in the air.

Part B

How lengthy after the arrowhead was shot need to the apple it is in dropped, in order because that the arrow to pierce the apple as the arrow hits the tree?
