The displacement of the object, as calculated from the area under a velocity-time graph showing constant acceleration, is 75 meters.
To determine the displacement of an object from a velocity-time graph, you can calculate the area under the graph line.
A velocity vs. time graph starting at 0 and ending at 10 m/s over a span of 15 seconds represents a straight line which indicates constant acceleration.
The area under this line is a triangle with a base of 15 seconds (t) and a height of 10 m/s (v), giving us an area of 1/2 * base * height = 1/2 * 15 s * 10 m/s = 75 m.
Therefore, the object's net displacement is 75 meters.
