which line shows both positive velocity and positive acceleration?\nline c\nline e\nline d\nline a\nline b
Answer
Explanation:
Step1: Recall velocity - acceleration concepts
Velocity is slope of position - time graph, acceleration is rate of change of velocity. Positive velocity means positive slope, positive acceleration means slope is increasing.
Step2: Analyze each line
- Line A: Slope = 0, velocity = 0, acceleration = 0.
- Line B: Slope = 0, velocity = 0, acceleration = 0.
- Line C: Positive slope (positive velocity), and slope is increasing (positive acceleration).
- Line D: Negative slope (negative velocity), slope is constant (zero acceleration).
- Line E: Negative slope (negative velocity), slope is constant (zero acceleration).
Answer:
Line C
