Question: During volcanic eruptions, chunks of solid rock can be blasted out of the volcano; these projectiles are called volcanic bombs. Figure shows a cross section

During volcanic eruptions, chunks of solid rock can be blasted out of the volcano; these projectiles are called volcanic bombs. Figure shows a cross section of Mt. Fuji, in Japan.

(a) At what initial speed would a bomb have to be ejected, at angle θ0 = 35o 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, for the moment, the effects of air on the bomb's travel.

(b) What would be the time of flight?
