Find what was the initial velocity of the arrow

Reference no: EM13647731

An arrow with a mass of 80 g is fired at an angle of 30 degree tothe horizontal. It strikes a target located 5 m above the firing point and impactsthe target traveling 20 m/s. If 10% of the initial energy of the arrow is lost toair resistance, what was the initial velocity of the arrow?
