An 478 kg sphere makes a perfectly in-elastic collision, Ask an Expert

Academics

A(n) 4.78 kg sphere makes a perfectly in-elastic collision with a second sphere that is initially at rest. The composite system moves with a speed equal to one-third the original speed of the 4.78 kg sphere.

What is the mass of the second sphere? Answer in units of kg.
