During a circus performance, a 64-kg human cannonball is shot out of an 17-m-long cannon. If the human cannonball spends 0.99 s in the cannon, determine the average net force exerted on him in the barrel of the cannon.

  • Physics - ,

    Force=mass*acceleration

    where acceleration=changevelocity/time
    but change velocity=Vf-0, or 2*avgvelocity=2*distance/time

    solve for force.
    force=mass*2*distance/time^2
