    Finding the tangential speed.... Help

    i got it, it I shouldn't have doubled my time. My answer is 4.65 m/s right?

    It's easier than you think. You have the angle the ball rotated. How much time did it take? (Hint the ball is travelling with a constant horizontal speed and the distance is given. Find the travel time.) Use this to find the angular speed ([itex]\omega[/itex]). Then use [itex]v = \omega r[/itex].
