A ferries wheel with radius 20 m which rotates counterclockwise, is just starting up. At a given moment, a passenger on the rim of the wheel and passing through the lowest point of his circular motion is moving at 3.00m/s and in gaining speed at a rate of . Find the magnitude of the passenger's acceleration at the instant.

 total accleration =( Ac^2 + At^2)^1/2  (Ac,At are centripital and tangential accleration)

               ={(v^2/r)^2+ a^2}^1/2

               v=3, a=0.5,r=20

  after substituting these values

          a=0.67 m/s^2
