When spiking a volleyball, a player changes the velocity of the ball from 4.5 m/s to -20 m/s along a certain direction.

If the impulse delivered to the ball by the player is -9.7 kg * m/s,
what is the mass of the volleyball?

  • Physics - ,

    momentum is P=MV
    P is impulse, which in this case is -9.7kg*m/s
    V is the change is velocity so (-24.7-5.2)
    so you just plug all this in the formula

    -9.7=(-24.7-5.2)m

    then just solve for "m" !

  • Physics - ,

    -0.33
