Textbook Question
Chapter 24, Problem 5RQ
If you are riding a bike at 10.0 m/s and throw a ball forward with a velocity of 4.00 m/s, will the ball travel 4.00 m/s relative to the ground, or will it travel at 10.0 m/s plus another 4.00 m/s relative to the ground? Explain your reasoning.

At an airport, Anna is stationary, Bert is walking at a speed of 1.0 m/s, Carla is standing while Dodong is walking on a platform that moves with a speed of 2.0 m/s. Anna observes Bert, Carla, and Dodong moving away from her in the same direction. Anna observes Dodong moving away from her at a speed of 3.0 m/s.
What is Anna’s velocity relative to the ground or earth?
You encounter a moving walkway that is 81 m long and has a speed of 2.1 m/s relative to the ground.
How long would it take you to cover the 81 m length of the walkway if, once you get on the walkway, you immediately turn around and start walking in the opposite direction with a speed of 1.6 m/s relative to the walkway?
Express your answer using one significant figure.
