Physics please help

A particle of mass m1, traveling at speed v0, collides head-on with a particle of mass m2 at rest. The collision is perfectly inelastic, i.e., the particles fuse together at the collision. Calculate the fraction of the initial kinetic energy dissipated in the collision. Assume the
collision is Newtonian, i.e., mass is conserved.
