give us the dimension and loading of you problem then we'll compare your answer will our answer.

Use the mechanical tool bar under menuctrls

Go to planetsourcecode.com to search for it.

Cp is usually the problem since they usually provide you with a Kilo unit

Normal Force = 1/2*(rho)(A)(CD)V^2 = 1/2*(rho)(12)CD(30^2) rho = air density CD = value of shape

Show us the picture then I think most of use will tell you the Volume.

just sum them up if the moment of inertia you looking at is on the same axis.

I don't know how to edit but. The equation I posted should be a = u/t instead. A Typo mistake there.

Opsss... Did I missed reading that the final velocity was 11.3 fps not 0 fps. --------- ----------- Well if you know the delta time when and after the impact then you can use the impulse equation, then multiply by delta time to get the answer. Else you can do it this way Sum (F) = ma a =...

Approximate: Sum of F = ma ads = vdv => v^2 = u^2 + 2as; u =0 a = v^2/2s => a = 11.3^2/2(2) => a = 31.92 ft/s^2 Sum of F = ma => Reaction = m*31.92 Aproximatelly I can't recall English unit; Substitute m as the mass of that thingo to find the approximate reaction.

another loss that would likely involved are the elastic strain energy.

The energy is lost do to frictions. Surfaces friction + aerodynamics friction.

Consider you have a dynamic loading on a plate overtime.

About the noise from the coconut. Due to impact noise are created.
