A 1.0 kg object is attached to one end of a 1.25 m long string. The other end of the string is fixed. The object is released from rest when the string is horizontal falls to a vertical 90-degree angle. What is the speed of the object as the lowest point along the path (when the string is vertical)? What is the value of the tension in the string at the lowest point? What is the work done by the...
3) A mass of 0.5 kg is attached to the lower end of a thin cord of which length is 2.1m. The upper end of the cord is fixed. The mass moves in a horizontal circle with constant speed. During the revolution of the mass, the cord makes a fixed angle of 20° with the vertical direction. As a result, the suspending cord traces out a cone. Determine the tension force F in the cord and the period T of...

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...
One end of a 0.80 m string is fixed, the other end is attached to a 2.0-kg stone. The stone swings in a vertical circle, passing the bottom point at 10 m/s. What is the radial acceleration of the stone at the top of the circle? (Ans: 86 m/s2)
A small object of mass 0.500 kg is attached by a 0.800 m-long cord to a pin set into the surface of a frictionless table top. The object moves in a circle on the horizontal surface with a speed of 8.17 m/s. a) What is the magnitude (m/s2) of the radial acceleration of the object? b) What is the tension (N) in the cord?
