When Using A Graph To Solve A Problem About How Far A Car Traveled During Specified Time During Which It Was Accelerating, How Many Area Calculations Do You Have To Make? What Is/are The Shape/shapes You Are Calculating?
( I believe the answer is D)
A. One area calculation, a rectangle. B. One area calculation, a triangle. C. Two area calculations, both triangles.
D. Two area calculations, a rectangle and a triangle.
We cant answer without looking at the graph.If it wsa constant velocity, then deaccelerated at a constant rate until stopped, then D is the answer.
You use of capital letters beginning each word is quite maddening.
To solve a problem about how far a car traveled during a specified time period while accelerating using a graph, you need to calculate the area under the graph. Acceleration is represented by a curve on the graph.
To calculate the area under the graph, you would need to divide the graph into segments. Each segment would represent a small time interval. The area calculations would be based on shapes that can be found within each segment of the graph.
In this case, when the car is accelerating, the graph would typically show a curve. To calculate the area under this curve, you would need to approximate the curve with various shapes.
The first shape you would need to calculate is a rectangle. You would find the height of the rectangle by looking at the graph and taking the value of the car's velocity at a specific time within the time interval. The width of the rectangle would be the length of that time interval.
The second shape you would need to calculate is a triangle. To do this, you would identify two points on the graph within the time interval and draw a line connecting them. The base of the triangle would be the length of the time interval, and the height would be the difference in velocity between the two points.
Therefore, the correct answer is D. Two area calculations, a rectangle and a triangle.
