Answer:
is his final displacement from the point A after 60 seconds.
Explanation:
Given:
Cyclist is moving away from A.
- velocity of cyclist,
- displacement of the cyclist from point A at the time of observation,
- time after which the next observation is to be recorded,
Now as the cyclist is moving away from point A his change in displacement after the mentioned time:
<u>Now the the final displacement from point A after the mentioned time:</u>
