Block A (0.40 kg) and block B (0.30 kg) are on a frictionless table (see figure) .Spring 1 connects block A to a frictionless peg at 0 and spring 2 connects block A and block B.When the blocks are in uniform circular motion about 0,the springs have lengths of and
,as shown.The springs are ideal and massless,and the linear speed of block B is 2.0 m/s.If the distance that spring 2 stretches is 0.060 m,the spring constant of spring 2 is closest to
