Re: How hard will a ball deflection hit?

I've got an update to our situation. We made a prototype out of plywood and 2x4s. We tossed the ball at it a few times. On the fourth impact, it split a 2x4 along the grain. Considering how strong the build looked I'm surprised by the damage. I think the lesson we learned was that there is more force imparted by a strong ball hit than you would probably expect. I'm glad this was a discovery in week 1 rather than week 3 or later.

It is interesting how similar that equation is to F = MA = M * Change in Velocity / Change in Time. It should be possible to calculate resulting vectors in a collision based on using the conservation of momentum and the conservation of energy.
