Suppose that the robotic manipulator is used in a space station to investigate zero-g manufacturing techniques. During an interval of lime, the manipulator is programmed so that the cylindrical coordinates of the 4-kg pail A are θ = 0.15t2 rad, r = 0.5(1 + sin θ) m, and z = 0.8(1 + θ) m. Determine the force vector exerted on A by the manipulator at t = 2 s in terms of cylindrical coordinates.
