Two balls (m= 3.0 kg and M=3m) are attached by light threads AO and OB (whose combined length l=1.0m) to a vertical axis at point O and set in rotational motion in a horizontal plane about this axis at a constant angular speed w. What is the ratio of the length AO and OB for which tensions in threads are the same?

Two 3.70 kg balls are attached to the ends of a thin rod of length 35.0 cm and negligible mass. The rod is free to rotate in a vertical plane without friction about a horizontal axis through its center. With the rod initially horizontal (the figure), a 76.0 g wad of wet putty drops onto one of the balls, hitting it with a speed of 1.37 m/s and then sticking to it. (a) What is the angular speed of the...

A bob of mass 0.320 kg is attached to one end of a light inextensible string of length 0.600 m, whose other end is attached to a fixed pivot. The bob performs uniform circular motion in a horizontal plane, with the string making an angle of 30.0° with the vertical. What is the angular speed of this circular motion? Give your answer in raduans. (Hint: you can begin by using Newton's second law in the vertical direction to find the...

Angular Momentum and Inelastic Collisions Two balls, each with mass M/2, are attached to the ends of a thin rod of length L = 0.45 m and negligible mass. The rod is free to rotate in a horizontal plane without friction about a fixed vertical axis through its center. With the rod initially at rest (as shown), two wads of wet putty hit the balls at the same time and stick to them. Assume that the wads of putty have...

A pendulum consists of a 2.5-kg bob attached to a light 1.2 m-long string. While hanging at rest with the string vertical, the bob is struck a sharp horizontal blow, giving it a horizontal velocity of 3m/s. At the instant the string makes an angle of 38 degree with the vertical, what is The speed, The tension in the string? What is the angle of the string with the vertical when the bob reaches its greatest
