Block a (0

question 24

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 spring constant of spring 1 is equal to 30 N/m, the unstretched length of spring 1 is closest to

• A) 0.51 m.
• B) 0.52 m.
• C) 0.53 m.
• D) 0.54 m.
• E) 0.55 m.
