13. a runner moves 200 meters east in 50 seconds. what is the runners velocity?
Answer
Explanation:
Step1: Recall velocity formula
Velocity (v=\frac{d}{t}), where (d) is displacement and (t) is time.
Step2: Identify values
Given (d = 200) meters (east - displacement has direction) and (t=50) seconds.
Step3: Calculate velocity
(v=\frac{200}{50}=4) m/s east.
Answer:
4 m/s east
