A 0.23 kg ball of dough is thrown straight up into the air with an initial velocity of 12 m/s.Find the momentum of the ball of dough halfway to its maximum height on the way up.

  • physics - ,

    KE at half height=
    1/2 m v^2=1/2 (1/2 m 12^2)
    or v= sqrt(1/2 144)=sqrt72

    momentum at half height:
    .23*sqrt72

    check that.
