Question

what is the total displacement of the car after 5 h?
0 km
15 km
20 km
40 km

Explanation:

Step1: Analyze the displacement - time graph

In a displacement - time graph, the displacement of an object at a particular time is given by the value on the y - axis (displacement axis) corresponding to that time on the x - axis.

Step2: Locate the time \(t = 5h\) on the graph

We look at the point on the graph where \(t=5h\). When \(t = 5h\), the value of displacement \(d\) on the y - axis is \(0\ km\). This is because the graph starts at \((0,0)\) and ends at \((5,0)\) (after going through some intermediate points). Displacement is a vector quantity that measures the change in position of an object from its initial point. If the object returns to its initial position (where it started), the displacement is zero.

Answer:

0 km
