E. Apparently MIT has lowered its standards and now has redneck physics (http://www.youtube.com/watch?v=cxvsHNRXLjw) .

IMHO this video would be much more useful if, instead of showing the same shot at different frame-rates and from different angles, it included at least three different 'muzzle velocities' with identical aiming and target height.


The UCSC version (or is the the Cabrillo College?) has a LASER pointer for aiming -- I didn't notice one in the MIT version.




Seeing then that the golf ball and monkey reach the same point at the same time would be more impressive.

High muzzle velocity => hit occurs high up.
Medium Muzzle velocity => hit occurs at mid height
Low muzzle velocity => hit occurs near ground

of course it would take some effort to get the three muzzle velocities 'just right'.



I beg your pardon.




(but the Red Necks in the Crowd would appreciate it.)
