Question:

Relative" is an important word. In Figure block L of mass mL = 1.00 kg and block R of mass mR = 0.500 kg are held in place with a compressed spring between them. When the blocks are released, the spring sends them sliding across a frictionless floor. (The spring has negligible mass and falls to the floor after the blocks leave it.)

(a) If the spring gives block L a release speed of 1.20 m/s relative to the floor, how far does block R travel in the next 0.800 s?

(b) It instead, the spring gives block L a release speed of 1.20 m/s relative to the velocity that the spring gives block R, how far does block R travel in the next 0.800s?
