Hi everybody,

I am trying to do sphere test on the simple . Can anyone has advice for this test. In this example I do not know time and velocity, the height is known, can I calculate velocity from these equations:

From these equations we can get that the velocity is: v = g*sqr(2*h*g);

Whether this can be used that calculates free fall sphere from height of 50 mm. From these equations I can see that the mass has not affect on the magnitude of the velocity. Do I need to use another equation to calculate velocity.

Or can I drop the sphere nearer the another part for reducing time for solving but that the sphere has the same velocity, which would simulate drop of the sphere from 50mm.

Does anyone know how to do this analysis.

Best regards.
