A particle is in uniform circular motion about the origin of an xy coordinate system, moving clockwise with a period of 7.00 s. At one instant, its position vector (from the origin) is 7 = (3.40 m )î – (3.70 m ). At that instant, what is its velocity in unit-vector - notation?

![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 0o = 41° to the
horizontal, from the vent at A in order to fall at the foot of the volcano at B, at vertical distance h = 3.20 km and horizontal distance
d = 9.70 km? Ignore, for the moment, the effects of air on the bomb's travel. (b) What would be the time of flight?
