  1. A mass is rotated through a horizontal plane ie., parallel to the ground as shown. Mass = 250g; time for half a revolution 6.7s; radius = 1.4m Show the tangential velocity is 6.6 ms-1 Calculate the centripetal acceleration. Calculate the unbalanced force.

  2. Mass = 250g; time for half a revolution 6.7s; radius = 1.4m Show the tangential velocity = 6.6 ms-1 v = v = v = v = 0.656 v = 0.66ms-1

  3. a = a = a = 0.307 a = 0.31ms-2 Mass = 250g; time for half a revolution 6.7s; radius = 1.4m 2. Calculate the centripetal acceleration.

  4. F = ma F = 0.25 x 0.31 F = 0.0768 F = 0.08N or F = m F = 0.08N Mass = 250g; time for half a revolution 6.7s; radius = 1.4m 3. Calculate the unbalanced force.
