While two astronauts (m1=46.1 kg and m2=84.2 kg) are floating in space, astronaut 1 decides it would be fun to push astronaut 2. If astronaut 2 has an acceleration of 2.26 m/s2, what is the acceleration of astronaut 1? Answer in units of m/s2 and be sure to include all necessary work, as well as a free body diagram for each astronaut. Help!!

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.)
