The space shuttle was used to repair satellites. Figure P8.16 illustrates how a crew member, with her feet strapped to the platform on the end of the shuttle’s robotic arm, used her arms to stop the satellite’s spin. The control system of the robotic arm has a closed-loop transfer function

(a) Determine the response y(t) to a unit step input, R(s)= 1/s. 

(b) Determine the bandwidth of the system.
