delta x (position) = h/4*pi*mdeltav.
delta x = h you know
4*pi you know
mass = 247 lb converted to kg.
delta v is 17.09 x 0.1 m/hr conerted to m/s.
Here is a site that does a pretty good job of explaining how to do this. I've also included another site that helps, too.

A 247 lb fullback runs the 40 yd dash at a speed of 17.09 ± 0.1 mi/h.
(a) What is his de Broglie wavelength (in meters)?
(b) What is the uncertainty in his position?
** I found part A but I am unsure how to use this information to get part B. Any help is appreciated :)
