Homework Statement
A single gas molecule of inertia m is trapped in a box and travels back and forth with constant speed v between opposite walls A and B a distance l apart. At each collision with a wall, the molecule reverses direction without changing speed.
Write algebraic expressions for the magnitude of the change in momentum of the molecule as it collides with wall B.
