In Figure, block 1 (mass 6.0 kg) is moving rightward at 8.0 m/s and block 2 (mass a.0 kg) is moving rightward at 2.0 m/s. The surface is frictionless, and a spring with a spring constant of 8000 N/m is fixed to block 2. Eventually block lover takes block 2. At the instant block 1 is moving rightward at 6.4 m/s, what are

(a) The speed of block 2 and

(b) The elastic potential energy of the spring?
