Johnny Jumper's favorite trick is to step out of his high-rise window and fall 55.0 m into a pool. A news reporter takes a picture of 95.0-kg Johnny just before he makes a splash, using an exposure time of 3.00 ms. Find the following. (a) Johnny's de Broglie wavelength at this moment m (b) the uncertainty of his kinetic energy measurement during such a period of time J (c) the percent error caused by such an uncertainty
