A 0.3 kg ball strikes a wall head on and then rebounds straight back. The initial speed was 10.0 m/s and the speed after it rebounds was 1.9 m/s. What was the magnitude of the total impulse on the ball during the collision in N*s?

  • Physics -

    impulse= mass(changeinvelocity)
    impulse=mass(1.9-(-10))=mass(11.9)
