Problem

Cart A (

m_A = 0.40\,\text{kg}

) moves at

+3.0\,\text{m}\,\text{s}^{-1}

toward cart B (

m_B = 0.60\,\text{kg}

), which moves at

-2.0\,\text{m}\,\text{s}^{-1}

. After they collide, cart A moves at

-1.0\,\text{m}\,\text{s}^{-1}

and cart B at

+1.0\,\text{m}\,\text{s}^{-1}

. Determine the total kinetic energy before and after the collision and state whether the collision is elastic, inelastic, or perfectly inelastic.
