Problem 1.2

A point traversed half the distance with a velocity v0v_{0}. The remaining part of the distance was covered with velocity v1v_{1} for half the time, and with velocity v2v_{2} for the other half of the time. Find the mean velocity of the point averaged over the whole time of motion.

Reveal Answer
⟨v⟩=2v0(v1+v2)/(2v0+v1+v2)\langle v\rangle=2 v_{0}\left(v_{1}+v_{2}\right) /\left(2 v_{0}+v_{1}+v_{2}\right)
