Projectile motion – Problem

Hi. Can you help me please? I have trouble with this question:


An arrow is aimed horizontally, directly at a target 17.2 meters away. when the arrow is released, it lands 0.08 meters below the target point. How long was the arrow in the air? How fast was the arrow moving when it left the bow?Nadia asked

Answer

Consider vertical motion. Take y =1/2 gr^2=0.08m and find t

Considering horizontal motion, find Vx from the relation x =Vx t

Find Vy =gt

Find V =√{Vx^2+Vy^2}
