AN oxygen atom is four times as massive as a helium atom. In an expriment of helium atom and an oxygen atom have the same kinetic energy. WHat is ratio V(He)/V(o) of their speed?

Think about what the terms are, and how they are related.

 

What does "massive" mean?

What is kinetic energy?

How do these relate to a body's speed?
