Fastened to a wall a second ob- ject, m2 5 7.00 kg, is slowly pushed up against m1, compress- ing the spring by the amount a 5 0.200 m (see fig. p12.67b). the system is then released, and both objects start moving to the right on the frictionless surface. (a) when m1 reaches the equilibrium point, m2 loses contact with m1 and moves to the right with speed v. deter- mine the value of v. (b) how far apart are the objects when the spring is fully stretched for the first time.
