) A neutral pion with rest mass 135MeV /c2 is traveling with speed 0.5c as measured in a lab. The pion then decays into two photons, one moving in the same direction as the original motion of the pion and the other moves in the opposite direction with energy 39MeV , as measured in the lab frame. (a) What is the energy and wavelength of the photon that moves in the same direction as the pion

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
