Question

4. Suppose the observed motion of a moving airplane, illustrated by a distance vs. time graph, is nearly a straight line with zero distance traveled at zero time. State what this shows about the relationship between distance and time, name the type of relationship, and tell what it indicates about the speed of the airplane.

Answer 1

It shows that the airplane covers equal distance in equal time interval, that's it has a straight line from the origin.

The plane is moving at uniform speed.
