An arrow is shot at an angle of 45 degrees above the hortizontal. The arrow hits a tree ditance D= 220m away, at the same height aboventhe ground as ut was shot. Use g = 9.8m/s2 for the magnitude of the acceleration due to gravity. Find ts, the time that the arrow spends in the air. Find the intial upwars compnent of the velocity in terms of D. find the time of flight in terms of the intial vertical component of velocity.
