Final answer:
The displacement of a plane can be calculated from the graph of velocity versus time by finding the area under the graph.
Step-by-step explanation:
The displacement of a plane can be calculated from the graph of velocity versus time. Displacement is the change in position of an object, which can be represented by the area under the velocity versus time graph. To calculate the displacement, you need to find the area enclosed by the graph.
To find the area under the graph, divide it into simpler shapes, such as rectangles or triangles. Then, calculate the area of each shape and sum them up. The resulting value will be the displacement of the plane.
For example, if the graph consists of a triangle and a rectangle, find the area of the triangle by multiplying the base and height and divide it by 2. Then, find the area of the rectangle by multiplying the base and height. Finally, add the two areas together to obtain the displacement.
