A baseball whose mass is 0.25kg is struck by a bat. just before impact, the ball is traveling horizontally ay 40m/s to the left and it leaves the bat at an angle of 30 degrees above the horizontal with a speed of 60m/s.
if the ball and bat were in contact for 0.05s, find the horizontal and vertical component of the average force on the ball?
state the impulse of the ball on the bat?
write the net impulse in vector notation.

  • Physics -

    work this in both directions:
    Impulse=force*time=mass(Vf-Vi) note Vf, Vi are in opposite directions, so they add.
