Arocket is launched vertically from a point on the ground. an observer who is 1000 m away from the base of the launching pad, notices that the angle of elevation of the rocket is increasing at a rate of π/40 radians per second when the angle of elevation is π/3.
find the speed of the rocket at that instant.
