    Numerical Analysis of BatBall Collision Performance in

    ball is not constant during contact, but it follows more of a sine-squared time history, starting and ending at zero and peaking approximately half way through the duration of contact. Although this collision maybe considered as one-dimensional only, but n reality, most collisions between bat and ball collisions require a two-dimensional analysis.
