2. If two particles have equal kinetic energies, does that mean that they must have equal momenta? Explain.

Solution Preview

No.

Momenta is a vector quantity, therefore it has direction which has an important role when discussing momentum.

Energy is a scalar - it has no direction. The energy is the dot product of the velocity with ...
