A mass mis attached to a spring which is held stretched a distance xmax by a force Fmax (see figure), and then released. The spring compresses, pulling the mass. For the following answers, assume that there is no friction. Use m for the mass, x for the distance xmax and F for the force Fmax- m x = 0 (a) Determine the speed of the mass m when the spring returns to its normal length (x = 0).
