A 87 g arrow is fired from a bow whose string exerts an average force of 105 N on the arrow over a distance of 76 cm.

1. What is the speed of the arrow as it leaves the bow?

  • Physics -

    force*time= mass*velocity

    but time = distance/avgvelocity= distance/finalvelocity/2=2*distance/Vf

    2*force*distance= mass*Vf^2

    Vf^2=2*force/mass * d
