Question

1. if a cyclist travels 100 meters north in 20 seconds, what is their velocity?

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
