Question

The graph below represents the motion of an object traveling in a straight line.

What is the average speed, in m/s to the nearest tenth, of the object during the first 4 seconds?

Answer 1

0.5 m/s

Step-by-step explanation:

average speed = distance / time

In the the first 4 seconds, the object moves from 0 m to 2 m. Therefore, the average speed is:

s = (2 m − 0 m) / 4 s

s = 0.5 m/s
