Problem
During an experiment a body moves in a straight line with the following velocity–time variation: for the first 5s its velocity remains constant at 10ms−1; during the next 5s the velocity decreases uniformly to zero.
(i) Describe qualitatively the shape of the velocity–time graph for the entire 10s interval.
(ii) Calculate the total displacement of the body in this interval.
(iii) Sketch the corresponding position–time graph, marking clearly the change in curvature, and explain what this curvature tells you about the nature of acceleration in each part.
