![2. A block of mass m is attached to a cord of length L, which is fixed at one end. The mass moves in a horizontal circle on a frictionless table. A second block of mass 3m is attached to the first by a cord of the same length L and also moves in a circle, as shown. The period of the motion is t. a. Write out the forces in the radial direction on each block. Given [m, L, t] calculate: b. The tension in the inner cord? c. The tension in the outer cord? d. The velocity of the outer block? e. The acceleration of the outer block? 3m](http://img.homeworklib.com/questions/52711340-c961-11ea-ad0a-05c89ab659eb.png?x-oss-process=image/resize,w_560)

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 ball with mass m= 0.98 kg, is attached to a horizontal cord of length l = 59 cm whose other end is fixed. A peg is located a distance h = 12 cm directly below the point of attachment of the cord. After the ball is released, what will be the tension (in N) in the cord when it just starts its circular path about the peg?

A small block with a mass of 0.0600 kg is attached to a cord passing through a hole in a frictionless, horizontal surface (Figure 1). The block is originally revolving at a distance of 0.49 m from the hole with a speed of 0.77 m/s . The cord is then pulled from below, shortening the radius of the circle in which the block revolves to 9.0×10−2 m . At this new distance, the speed of the block is 4.19 m/s...
