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.

    find the resultant velocity with the conservation of momentum

    m1*vo=(m1+m2)V

    solve for V

    determine finalKE, and initial KE, and the fracation.

    the difference between final and initial KE is lost ke, the fraction would be that amount lost divided by initial

    KE=0.5MV
