5) A collar B of mass m slides on the frictionless arm AA'. The arm is attached to drum D and rotates about O in a horizontal plane at the rate 0= ct, where e is a constant. As the arm drum assembly rotates, a mechanism within the drum winds in the cord so that the collar moves toward O with a constant speed k. Knowing that at 0, 1 =To express as a function of m. e. k. ro, and t a) the tension I in the cord, b) the magnitude of the horizontal force Q exerted on B by arm AA'.
