Block (0.40 kg) and block (0.30 kg) are on a frictionless table (see figure). Spring 1 connects block to a frictionless peg at 0 and spring 2 connects block and block . When the blocks are in uniform circular motion about 0, the springs have lengths of 0.60 m and 0.40 m, as shown. The springs are ideal and massless, and the linear speed of block is 2.0 m/s. If the spring constant of spring 1 is equal to 30 N/m, the unstretched length of spring 1 is closest to

0.55 m.

0.54 m.

0.51 m.

0.53 m.

0.52 m.

Block (0.40 kg) and block (0.30 kg) are on a frictionless table (see figure). Spring 1 connects block to
a frictionless peg at 0 and spring 2 connects block and block . When the blocks...
