Two athletes are running toward the pole vault. One is running at 3.8 m/s and the other is running at 4.3 m/s.

a) What is their velocity relative to each other?
b) If they leave the ground at their respective velocities, which one has the energy to go higher in the vault?

4.3-3.8

0.5 m/s

one with 4.3 m/s because energy is proportional to velocity
