Problem 4. (1 point) Two blocks with masses m1=2.7kg and m2=4.4kg are at fest on a frictionless surface with a compressed spring between them. The spring is initially compressed by 620cm and has negligible mass. When both blocks are releaved samultaneously and the spring has dropped to the surface, m1 is found to have a speed of 2.3m/s. What is the speed of m2 ? What is the spring constant of the spring? Answrr(x) subeitted: - no response - no response - no response - no response submitted: (incorrect) recorded: (incorrect)
