During a circus performance, a 75-kg human cannonball is shot out of an 19-m-long cannon. If the human cannonball spends 0.94 s in the cannon, determine the average net force exerted on him in the barrel of the cannon

  • Physics -

    V = 19 m / .94 s = 20.2 m/s,
    V = at,
    a = V / t = 20.2 m/s / 0.94 s = 21.5 m/s^2,
    F = ma = 75 kg * 21.5 m/s^2 = 1613 N.

  • Physics -

    that was wrong
