A 1.34 kg ball is connected by means of two massless strings, each of length L = 1.70m, to a vertical, rotating rod. The strings are tied to the rod with separation d=1.70 m and are taut. The tension in the upper string is 35 N.

a) Draw the free body diagram of the ball. Choose an appropriate

set of axes (explain your choice) and draw a component diagram

with respect to the axes you have chosen.

What are the:

b) Tension in the lower string

c) The magnitude of the net force on the ball and

d) Speed of the ball

e) What is the direction of the net force on the ball
