A 225 gram arrow is shot vertically into the air from an initial height of 1.40 meter above the ground with an initial speed of 18.6 m/s. When it reaches a height of 4.60 meter above the ground, its velocity is measured to be 9.74 m/s upward. Air resistance is not negligible. During the time interval between shooting the arrow and measuring its velocity at 4.60 m, find the amount of mechanical energy dissipated by air friction?
