Block Acan move without friction in the slot as shown and is acted upon by a vertical periodic force of magnitude P = Pmsin ωft, where ωf=2 rad/s and Pm = 20 N. A spring of constant kis attached to the bottom of block Aand to a 22-kg block B.Determine (a) the value of the constant kwhich will prevent a Steady-state vibration of block A.(b) the corresponding amplitude of the vibration of block B.
