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 before the impact of the 15lb 2x4. How much additional weight is needed to be added to the 2x4 to achieve the 67 mph just before impact? Also what formulas are used to get this answer?
