You shoot an arrow straight up into the air using a bow. You have pulled the bowstring back by a distance of 0.5 m, using 30 N of force. The arrow has a mass of 0.25 kg.

How high in the air will it go?

Constant force? That is not usual with a bow. But assuming constant force,

work=PEgained
F*d=mgh
solve for height h.
