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

force*time=mass*changeinVelocity

now the average velocity is 19/.94 m/s
so the final velocity has to be twice that.
