Question

The graph represents the motion of an object. How many total meters did the object travel?

Answer 1

Answer:

Yup ur right its B.

Answer 2

Answer:

the answer is C. 120 meters

Explanation:

The total distance covered by the object is 120 meters because;

1. distance is a scaler quantity, thus it does not take into consideration the  of direction of the distance covered by the body.
2. in the rising part of the graph from the origin, the distance in other words the total meters travelled by the object was 10meters+50meters(60meters).
3. in the declining part of the graph the object also 50meters back and another 10 meters also making the total distance covered for the declining journey also 60 meters.
4. note that in the rising part of the graph the body covered 10 meters and then stopped moving and later started moving for another 50 meters then stopped moving again before initiating the declining phase or how I'll call it the returning phase.
5. so in all the total journey covered is 60 meters from the rising phase of the graph and another 60 meters from the declining phase of the graph also making it (60meters + 60meters) 120 meters in all.

Hope you are convinced. :)
