A puck of mass m = 53.0 g is attached to a taut cord passing through a small hole in a frictionless, horizontal surface (see figure below). The puck is initially orbiting with speed V = 1.40 m/s in a circle of radius 1 0.320 m. The cord is then slowly pulled from below, decreasing the radius of the circle to r= 0.140 m. (a) What is the puck's speed at the smaller radius? m/s (b) Find the tension in...

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...
