5.5 The Mathematics of Speed

Problem

## Module 05: The Mathematics of Speed - Problem Set 1

Let’s get some more practice with the new velocity combination law. Imagine that you have a multistage rocket in which the first stage blasts off from the ground at $v_1$, the second stage blasts off later with speed $v_2$ relative to the first stage, and the third stage blasts off later still with speed $v_3$ relative to the second stage.
