    Impulse question.

    A baseball play swings his bat and hits a ball of mass m as shown below. Initially the ball was travelling with a speed v in a horizontal direction. Afterwards the ball has the same speed but is travelling back the way it came but at an angle above the horizontal. What is the magnitude of the impulse which acts on the ball?

    Start with the definition of impulse: \text{Impulse} = \Delta \vec{p} = m \Delta \vec{v} since mass does not significantly change.
