which time interval shows the object decelerating? 10 - 15s 20 - 25s 0 - 5s 5 - 10s
which time interval shows the object decelerating? 10 - 15s 20 - 25s 0 - 5s 5 - 10s
Answer
Explanation:
Step1: Recall deceleration concept
Deceleration means decrease in velocity. On a velocity - time graph, it is shown by a negative slope.
Step2: Analyze each interval
0 - 5s: Positive slope (acceleration). 5 - 10s: Zero slope (constant velocity). 10 - 15s: Negative slope (deceleration). 20 - 25s: Negative slope but we are looking for the first decelerating interval.
Answer:
10 - 15s
