at what position does the runner stop running to rest? a 0 m b 140 m c - 50 m
Answer
Explanation:
Step1: Identify the end - point of motion
Look at the position - time graph. The runner stops running when the slope of the graph becomes zero (indicating zero velocity, i.e., at rest).
Step2: Read the position value
At the point where the runner stops (the flat - part of the graph), read the corresponding position value on the position axis. From the graph, it can be seen that the position is 0 m.
Answer:
0 m
