Let 61 = 26 Figure 1: Diagram for Question 1 Question 1: 25 points A 1 kg ball is guided along a circular path in the vertical plane. The length of the arm 0A is given by equal to TWO 2 2rc cos0 using the arm OA. If the arm has an angular velocity of 0 = 0.6 rad/s and an angular acceleration 0 = 0.5 rad/s2 at the instant 0 = 1r / 6 rad, determine the force of the arm on the ball. Neglect friction, air resistance, and the size of the ball. rC = 0.6 ft
