an arrow of mass .04 kg is pulled back 10 cm in the bow, having a force of 25.2 N. It is released 1.5m from the ground...how far will the arrow fly?
(all of the energy from pulling it back converts into the flying arrow)

  1. This problem is missing information.

    If the pull force is constant:
    pulled 0.10 meters * 25.2 = 2.52 Joules
    .5 m u^2 = 2.52 Joules
    solve for u

    however if the bow behaves like a spring

    then average force = 1/2 * max force
    and we get 1.26 Joules

    You do not say which

    If you fire horizontally
    solve vertical problem to find time in air
    (1/2) g t^2 = 1.5 meters
    solve for t
    then
    horizontal distance = u t

    If you fire up at 45 degrees (max range) it is a little more complicated but again solve the vertical problem for time, then do the horizontal problem for distance.
