It is possible to shoot an arrow at a speed as high as 80 m/s. If friction is neglected, how high would an arrow launched at this speed rise if shot straight up? How long would the arrow be in the air?

    That is a typical arrow speed from a performance bow.

    How high?

    vtop=vinitial-g (time
    time=80/9.8 seconds to the top, so double that to get total time in air.

    Remember, you are neglecting air friction, which is considerable on those feathery things.

    so how high does it go?
    I cant figure it out
