Problem

Two separate experiments are performed on a frictionless track. • Collision I: A

1.0\,\text{kg}

cart moving at

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

collides and sticks to an identical

1.0\,\text{kg}

cart that is initially at rest. • Collision II: A

2.0\,\text{kg}

cart moving at

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

collides and sticks to a

1.0\,\text{kg}

cart that is initially at rest. Which collision results in the larger fraction of the system’s initial kinetic energy being converted to other forms? a) Collision II only b) Collision I only c) Both collisions convert the same fraction of energy d) There is not enough information to decide
