Two particles of mass m1= 2.6 kg and mass m2 = 4.8 kg that are free to move on a horizontal track are initially held at rest so that they compress a spring as shown in the figure below. The spring has a spring constant k = 395 N/m and is compressed 0.10 m. Find the final velocities of the two particles.
v1 = m/s
v2 = m/s
