Stage 3: position of pivot point p for rotating boom in this stage, your task will be to extend the kinematics of point p to include rotation of the boom. when the boom rotates through angle θ, the position vector developed in task 2 can be expressed in term of the cylindrical coordinates(r, θ) for the fixed (x, y) coordinate system where:

the correct answer is c.stops after infancy and childhood.
