Question

15. What does the slope of each line in the given position vs time graph represents? a. The speed of each runner b. The time of each runner c. The distance of each runner d. The acceleration of each runner​

Answer 1

Explanation:

principle is that slope of line on position-time graph = velocity of object. if object is moving with velocity of +4 m, then slope of line will be +4. if object is moving with velocity of -8m, then slope of line will be -8 m
