    Volleyball Impulse and momentum problem

    can someone explain to me how to start on this problem A volleyball is spiked so that its incoming velocity of +4.1 m/s is changed to an outgoing velocity of -18 m/s. The mass of the volleyball is 0.44 kg. What impulse does the player apply to the ball?

    Model Rocket Impulse and momentum problem

    ok i plugged the formula ..initial v is 0 final v is 27.5 the mass is 0.173 0+27.5=0.173 This is the formula 27.5Ns/0.173kg=159

    Model Rocket Impulse and momentum problem

    A model rocket is constructed with a motor that can provide a total impulse of 27.5 N · s. The mass of the rocket is 0.173 kg. What is the speed that this rocket achieves when launched from rest? Neglect the effects of gravity and air resistance. i know that the equation is p=mv (vector...
