position A, where the two horizontal attached springs are unstretched. The ball
follows the dashed path shown and crosses point B, which is 12 cm. directly below
A. Calculate the velocity of the ball at B. Each spring has a stiffness of k = 1 ª

A small 0.490-kg object moves on a frictionless horizontal table in a circular path of radius 2.50 m. The
angular speed is 3.83 rad/s. The object is attached to a string of negligible mass that passes through a small
hole in the table at the center of the circle. Someone under the table begins to pull the string downward to
make the circle smaller. If the string will tolerate a tension of no more than 123 N, what is the radius of the
smallest possible circle on which the object can move?
