To Choose: The correct option.
Answer to Problem 3STP
A correct answer is an option (C).
Explanation of Solution
Given:
From above graph, it is found that,
Distance travelled by the cyclist is
Initial speed of the cyclist is
Formula used:
The average speed is
Here,
Calculation:
The speed of the cyclist is zero at a distance of 3 km and 5 km after starting of the journey. The graph indicates the speed is zero at this point of distance on the x axis. So the options (a), (B), and (D) are wrong.
The cyclist has speed zero at two locations in the graph given above. So, option (C) is correct answer.
Conclusion:
Hence, the cyclist stopped 2 times.
