Two particles of the same mass are attached to the ends of a spring of negligible mass, initially with its relaxed length l0. The spring is stretched to twice that length and is released after there are equal and opposite velocities (v0; v0) the particles, perpendicular to the direction of the spring, such that kl02 = 6mv02, where k is the constant of spring. Calculate the radial and transverse components (vr; v) of the particle velocity as the spring returns through its relaxed length.
