13) if a cyclist travels 100 meters north in 20 seconds, what is their velocity?
Answer
Explanation:
Step1: Recall velocity formula
Velocity $v=\frac{d}{t}$, where $d$ is displacement and $t$ is time.
Step2: Identify values
$d = 100$ meters (north - indicates direction), $t=20$ seconds.
Step3: Calculate velocity
$v=\frac{100}{20}=5$ m/s north.
Answer:
5 m/s north
