John Wayne was striding down Main Street when a 9.5 kg bar stool came flying down out of a second story saloon window at 4.0 m/s at an angle of 25 degrees to the ground. Unbelievably quick on the draw, Mr. Wayne pulled out his trusty monster magnum and fired off a 42 gram slug upward at an angle of 15 degrees to the street level. If the stool was stopped dead in its (horizontal) tracks by the bullet (which...
