Asked by Sam
During volcanic eruptions, chunks of solid rock
can be blasted out of the volcano; these projectiles
are called volcanic bombs. The Figure shows a
cross section of Mt. Fuji, in Japan.
(a) At what initial speed would a bomb have to
be ejected, at angle q0 = 35° to the
horizontal, from the vent at A in order to fall at the foot of the volcano at B, at vertical
distance h = 3.30 km and horizontal distance d = 9.40 km? Ignore the effects of air on the
bomb's travel.
(b) What would be the time of flight
