1. In a high temperature experiment an ozone molecule, O3,
moving right at 1.5 × 103 m/s, collides head-on with an oxygen
molecule, O2, which is moving to the left at 400 m/s. Both of these
velocities are for the molecules viewed from the Earth frame. No
chemical reaction takes place but the ozone becomes “vibrationally
excited” during the interaction so that its internal energy
increases by 1.4 × 10−20 J. You will need the inertias of the
molecules, but...
