Block a (0

question 33

Multiple Choice

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 0.60 m and 0.40 m, 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 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 0.60 m and 0.40 m, 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   A)  18 N/m. B)  20 N/m. C)  22 N/m. D)  24 N/m. E)  26 N/m.
