## Homework Statement

Two blocks are free to slide on a frictionless wooden track ABC shown in figure. The block of mass m1=5.00kg is released from A. The block of mass m2 = 10.0kg is initially at rest. The block of mass m1 collides with m2 and they start moving together.

## Homework Equations

What will be their speed after they started moving together? How much energy is lost as a result of the collision?

## The Attempt at a Solution

I know we use the conservation of momentum ( m_1*v_1 = m_1*v_f + m_2*v_2). I also know that this is an elastic equation where we can use the equation for conservation of kinetic energy.
