1. The problem statement, all variables and given/known data "Relative" is an important word. Block L of mass mL = 1.90 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 1.80 m/s relative to the floor, how far does block R travel in the next 0.800 s? correct check mark m (b) If, instead, the spring gives block L a release speed of 1.80 m/s relative to the velocity that the spring gives block R, how far does block R travel in the next 0.800 s? 2. Relevant equations m1v1=m2v2 v=d/t 3. The attempt at a solution 1.9*1.8=.5*velocityR velocityR = 6.84 m/s d=v*time d=(6.84)(.8) d=5.472m Ok, so 5.472m is the correct answer for part A but I don't know how to get part B. Any suggestions???
