10. An object of mass mi
2.5 kg is connected to another object of mass m₂ = 4.0 kg by a compressed
spring. Both objects are at rest on a frictionless surface. When the spring is released, the objects are
pushed apart and a total energy of 16.8 J is given to the two objects. The speed of object m₁ is
