2. The strings AB and AC connect the 200 g ball to the vertical shaft, as shown in Fig. 2. The shaft rotates at a constant angular speed w and the ball travels in a horizontal circle with the strings inclined at a = 30° to the shaft. Given that the tension in string AC is 4 N. (a) Draw a free body diagram of the forces on the ball. (b) Calculate the radial acceleration of the ball. (c) Find the value of the angular speed w. (d) What is the tangential acceleration of the ball?
