The link below will show you how to run an optimization of the initial conditions for the ball. The motion study determines the best initial velocity needed for the ball to reach the target.

In the design study, you are telling SolidWorks to try a minimum initial condition, a maximum initial condition and the amount of attempts between the min and max values. The step is the resolution of the motion study. The smaller the step, the better your results, but the longer it will take SolidWorks to solve.
The constraint determines which boxes of the results are highlighted in pink. The pink boxes are the ones that do not meet the constraint(s) that you set. The grey boxes are the possible solutions to the problem. You might sometimes need to increase the step/resolution to get the results you want.
