Or am I looking for Kinetic Energy??

When I say impact, I mean just before the 2x4 would strike the surface.

I posted earlier about testing a project to simulate a wood 2x4 traveling at 67 mph, I did not really get the answers I was looking for so I am going to try to rephase it. My project needs to withstand the impact of a 15lb wood 2x4 traveling at 67 mph. I want to simulate this test but in a...

Does anyone have any other ideas how I can simulate this test other than the private road idea. Something a little more controlled.

And wouldn't the additional weight be a stored engergy?

So if i drop 1000lbs and 1 lb from the same height, they will land at the same time?

I am needing a project to withstand the impact of a 15lb wood 2x4 traveling at 67mph in a horizontal fashion. I want to test my project before the final test. I want to vertically drop a 15lb wood 2x4 fixed to additional weight at a height of 10ft. The additional weight will be released just...

Thank you very much!

To double check my work, a 41.25lb dropped from 20ft would equal 46 slug ft/sec. Correct?

Ok let me ask this then, if I were to drop 100lbs from 20ft, what would the speed(mph) be just before it hits the ground? What equation or equations are used to find this out?

I am researching a product that has to withstand a 15lb 2x4 that is shot from a pressurized air cannon traveling at 67mph at moment of impact . I want to mimick this test but I want to drop the object instead of using an air cannon. The height can vary as long as it is under 25ft and also the...

Homework Statement I have a problem where I need to know what the impact force of an object with a mass of 15lbs traveling at 67 mph would be? I also need to know at what height the same object would need to be dropped from to achieve this same impact force . Homework Equations Not sure...

Yes, am I missing something?

By adding weight to the object being dropped to achieve the desired impact force.

I have a product that needs to pass an impact test of a 6.8kg object traveling at 29.95 m/s. What I am wanting to do it recreate this situation but in a vertical fashion. The weight of the object can vary as long as I end up with the impact force.
