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 tension in the string.)

A pendulum is 0.864 m long and the bob has a mass of 1.04 kg. When the string makes an angle of θ= 14.8 degrees with the vertical, the bob is moving at 1.44 m/s. Find the tangential and radial acceleration components and the tension in the string. (Hint: Draw an FBD for the bob. Choose the x-axis to be tangential to the motion of the bob and the y-axis to be radial. Apply Newton's second law.) at = ______...

A stone with a mass of 0.700 kg is attached to one end of a string 0.800 m long. The string will break if its tension exceeds 50.0 N. The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string remains fixed. A. Find the maximum speed the stone can attain without breaking the string.
An inextensible massless string of length 2l has mass mand m3 attached to the two ends A and B respectively. A particle of mass m2 is attached to the midpoint of the string at point C. Initially, the three particles are at the vertices of an equilateral triangle as shown in the figure below and the string is taut. Particle 2 is given an impulse J along the bisector of the angle ACB. It is known that the whole set...
