Question

how long did it take this object to tom? 0s 10s 15s 20s

Explanation:

Step1: Identify position-time data

From the graph, the object reaches 10 m at $t=0\ \text{s}$, and stays at 10 m until $t=10\ \text{s}$.

Step2: Calculate time to travel 10 m

The time taken is the difference between the final and initial time when the object is at 10 m.
$t = 10\ \text{s} - 0\ \text{s} = 10\ \text{s}$

Answer:

10 s
