Test Your Knowledge: Take the Novice Beginning Physics Quiz!

AI Thread Summary
The discussion identifies an error in question 4 of the "Beginning Physics" novice quiz regarding the calculation of a cyclist's acceleration. The question presents a scenario where a cyclist changes velocity from 5 m/sec to 15 m/sec over 4.0 seconds. The correct calculation of acceleration, which is defined as the change in velocity over time and includes direction, is not accurately represented in the provided answer choices. The correct acceleration should be calculated as (15 m/sec - 5 m/sec) / 4.0 sec, resulting in 2.5 m/sec² [N]. This highlights the importance of ensuring accuracy in educational materials.

Near the top of this web page, there is a link to a quiz. If you take the Novice quiz called "Beginning Physics", you will find an error in question 4:

Question: A cyclist changes velocity from 5 m/sec [N] to 15 m/sec [N] in 4.0 sec. What is the value of her acceleration?

a) 2.5 m/sec
b) 5 m/sec
c) 1.5 m/sec
d) 3.5 m/sec

Can you spot it? Highlight the text below for the answer.

Highlight this
Acceleration is length per time squared. And it has a direction, in this case [N].
