Hearing the noise of passing commuters, a sleeping giant discovers an interstate highway has been constructed at the foot of his mountain abode and goes down to investigate. Grabbing an oncoming double-decker bus, the giant pitches it at a precise 38° angle, causing it to land 145 meters away at the other end of the meadow.

Assuming negligent wind resistance, and using common knowledge of the hurling capacity of giants, calculate how many passengers were aboard.
