Question

4.A 4kg object is connected by means of two massless springs to a vertical, rotating rod as shown in figure 6.31 in your book (problem 54). The strings are tied to the rod and are taut. The tension in the upper strings is 32N. Draw the FBD for the ball. What is the tension in the lower ring? What is the magnitude of the net force on the ball? What is the speed of the ball? Tension in Lower String 4L.4g Magnitude of N 1.25 Speed: 4. 3 -ls T. sin Ticos Cos loD T Cosleo 30, 24 T, cos 23. a4 25 cos30 re 1.0 8 1.08 4.3 mls

Explanation / Answer

Yes you are doing it right now balance centrifugal force with components of tension of spring in horizontal plane to find speed of ball.
