A bar has the length of 0.78 meters. Its one end is xed at the point (0,0)m and the bar rotates in xyplane starting at time t : O s. At time t : 0 s the bar is on the x-axis. The angular velocity is co = 0.455'1 . Positive value is counterclockwise rotation. (3) Calculate xcoordinate of the free end of the bar at 2.2 seconds to two decimal places. (b) When will the free-end ycoordinate be 0.58 meters rst time after t = 0 3? Use two decimal places in your answer. (a) x=:m a =
