A puck of mass `m = 50.0 g` is attached to a taut cord passing through a small hole in a frictionless, horizontal surface (Fig.) The puck is initially orbiting with speed `v_i = 1.50 m//s` in a circle of radius `r_i = 0.30 m`. The cord is then slowly pulled from below, decreasing the radius of the circle to `r = 0.10 m`. The puck's speed at the smaller radius is.

A mass m is attached to a string passing through a small hole in a frictionless, horizontal surface. The mass is initially orbiting with a velocity v_(1) in a circle of radius r_(1) The string is then slowly pulled from below, decreasing the radius of the circles to r_2 (i) What is the speed of the mass when the radius is r_2 ? (ii) What is the tension in the string ? (iii) What is the work done in moving the mass m from r_(1) to r_(2) ?

A block of mass 0.1 kg is attached to a cord passing through a hole in a horizontal frictionless horizontal surface as shown in the figure. The block is originally revolving at a distance of 0.4 m from the hole, with an angular velocity of "2 rad s"^(-1) . The cord is then pulled from below, shortening the radius of the circle in which the block revolves to 0.2 m. Considering the block to be point mass, calculate the new angular velocity ("in rad s"^(-1))
