3) Two plane mirrors are set so they create a 90° angle between them (like in a corner). A ray of light
strikes one mirror at an angle of 60° to its normal. Determine the angle of reflection with respect
to the other mirror's normal. (Strikes one mirror, then reflect onto the other mirror, the reflects
off that mirror)

Acatapult is tested by roman legionnaires. they tabulate the results in a papyrus and 2000 years later the archaeological team reads (distances translated into modern units): range = 0.4 km; angle of launch = π/5 rad; landing height = launch height. what is the initial velocity of launch of the boulders if air resistance is negligible?
