The correct Answer is:
To determine which velocity-time graph represents a realistic situation for a body in motion, we need to analyze the characteristics of velocity-time graphs. ### Step-by-Step Solution: 1. **Understanding Velocity-Time Graphs**: - A velocity-time graph plots velocity (y-axis) against time (x-axis). - At any given moment in time, a body can only have one velocity. This means that for any specific time value, there should be a single corresponding velocity value. 2. **Analyzing Each Option**: - **Option A**: Check the graph for multiple velocities at a single time point. - If there are multiple velocity values at the same time, this graph is unrealistic. - **Option B**: Check if there is a single velocity for each time point. - If this graph shows one velocity for each time, it is a realistic representation. - **Option C**: Similar to Option A, check for multiple velocities at the same time. - **Option D**: Again, check for multiple velocities at the same time point. 3. **Conclusion**: - After analyzing all options, we find that Options A, C, and D show multiple velocities at the same time, which is not possible in reality. - **Option B** is the only graph that shows a single velocity for each time point, making it the only realistic situation for a body in motion. ### Final Answer: - **Option B** is the correct answer as it represents a realistic situation for a body in motion.
