Andrew kicks a ball along a straight path. the ball rolls straight forward for 13.2 meters. then andrew kicks the ball straight back. the ball rolls back along the same path for 9.5 meters. what distance did the ball travel?

3.7 meters
0 meters
22.7 meters
125 meters

22.7 meters

Explanation:

Let's remind the difference between distance and displacement:

- distance: the total distance travelled by an object in all its paths

- displacement: the different between the final and initial position of the object

In this case, the problem asks to find the distance covered by the ball. This will be the sum of the distances covered by the ball in each part of its motion, therefore:

(instead, the displacement will be the difference between the final and initial position of the ball, therefore:

)

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
