Physics for Scientists and Engineers 3rd Edition by Randall Knight, Chapter 1 Exercise and Problems 2


A rocket is launched straight up. Draw a basic motion diagram, using the images from the movie, from the moment of liftoff until the rocket is at an altitude of 500 m.


Solution:

Model

We have no information about the acceleration of the rocket, so we will assume that it accelerates upward with a constant acceleration.

Solve

Assess

Notice that the length of the velocity vectors increases each step by approximately the length of the acceleration vector.
