    Solving Head-On Collision: Find Ball Speed w/o Knowing Bat Mass

    You can express the final expression for the velocity of the ball as function of M_ball/M_bat. This can be taken as zero as M_ball<<M_bat

    How do the d terms in differential equations work?

    The integral of d2y is dy. Once again integrating you will get y. The way you are rewriting the equations can make confusion. To avoid this confusion rewrite d2x/dx2 as d/dx(dy/dx). Now you can integrate two times with respect to x.
