Two blocks of masses 1.0 kg and 3.0 kg connected by a spring rest on a frictionless surface. If the two are given velocities such that the first travels at 1.7 m/s toward the center of mass, which remains at rest, what is the velocity of the second?
Take the mass of the sun to be m_s = 1.99×1030 {rm kg}, gravitational constant to be G = 6.67×10-11 {rm N} cdot {rm m^2/kg^2}, and an acceleration due to gravity at the earth's surface to be g = 9.810 {rm m/s^2}.
