A 0.077-kg arrow is fired horizontally. The bowstring exerts an average force of 50 N on the arrow over a distance of 0.75 m. With what speed does the arrow leave the bow?

  • physics - ,

    The work done by the bow string, F * X = 50 x 0.75 Joules,
    equals the kinetic energy (MV^2/2) of the arrow as it leaves the bow.

    Solve for V
