The velocity of a sports car is graphed as a function of time . Use the graph to answer the questions.
a) Find the sports car’s maximum velocity, , during the 10- interval depicted in the graph.
b) During which time interval is the acceleration positive?
To find the maximum velocity during the 10-second interval depicted in the graph, you need to look for the highest point on the graph. The y-axis of the graph represents velocity, so find the highest point on the y-axis during the given time interval.
To determine the time interval during which the acceleration is positive, you need to examine the slope of the graph. The slope of the graph represents acceleration, so look for sections of the graph where the slope is positive.
Without seeing the actual graph or having more specific information, I am unable to provide a precise answer. However, I can guide you through the process of finding the answers using the graph you have.
1. Look for the highest point on the graph within the 10-second interval. Find the point that represents the maximum value of velocity (usually the highest point on the graph).
2. Note the time at which the maximum velocity occurs. This will give you the answer to part a).
3. Look at the different sections of the graph and observe the direction of the slope. If the slope is increasing (moving upwards), then the acceleration is positive. Identify the time intervals where the slope is positive and note the corresponding time values.
By following these steps, you should be able to find the maximum velocity during the 10-second interval and determine the time interval during which the acceleration is positive.
To answer the questions, the graph of the velocity of the sports car as a function of time is needed. Unfortunately, as a text-based AI, I am unable to see or analyze any graphical information. However, I can provide you with a step-by-step explanation of how to analyze the graph to find the answers.
a) To find the sports car's maximum velocity during the 10-second interval depicted in the graph, you would need to locate the highest point on the graph within that interval. The highest point represents the maximum velocity. The value on the y-axis at that point would give you the maximum velocity of the sports car.
b) To determine during which time interval the acceleration is positive, you would need to examine the slope of the graph. Positive acceleration occurs when the slope of the graph is positive, indicating an increase in velocity over time. You would need to identify the sections of the graph where the slope is positive, indicating positive acceleration.
Without the graph or specific numerical values, I cannot provide more precise answers. If you can provide further details or describe the graph, I'd be happy to help you with the calculations based on the given information.
