Undergrad How to Simulate a 15lb Wood 2x4 Impact at 67 mph?
Moose, this is how I would go about it: 1. Figure out how fast the object is moving when dropped from 15 feet. This can be done with the known acceleration due to gravity (32.2 ft/s^2). This is the average acceleration across the Earth's surface. If you wanted a more accurate number, you'd... -
