Question

An archer standing on the back of a pickup truck moving at 28 m/s fires an arrow straight up
at a duck flying directly overhead. The archer misses the duck! The arrow was fired with an
initial velocity of 49 m/s relative to the truck.
(a) For how long will the arrow be in the air?
(b) How far will the truck travel while the arrow is in the air?
(c) Where, in relation to the "duckless" archer, will the arrow come down? Will the archer
have to 'duck'?
