CAN SOMEONE PLEASE HELP ME WITH MY PHYSICS QUESTIONS? I NEED CORRECT ANSWERS ONLY! I ALSO NEED SOMEONE TO HELP ME WITH MORE QUESTIONS
Sally walks 10 meters forward and then 5 meters backwards. Which statement most accurate describes the magnitude of her displacement and distance travelled?

A) Sally's displacement is 5m less than her distance travelled.

B) Sally's displacement is 10m less than her distance travelled.

C) Sally's displacement is 5m greater than her distance travelled.

D) Sally's displacement is 10m greater than her distance travelled.

Answer 1

Sally started at the starting point.

She walked 10m forward.  So far, she walked 10m, and she was 10m from the starting point.

Then she walked 5m backward.  So far, she walked 15m, but she was only 5m from the starting point.

The distance she walked was 15m.  But her displacement is how far she is from the starting point ... that's only 5m

Displacement = 5 meters

Distance = 15 meters

Displacement is 10m less than distance walked.  (B)

===> If she kept going and walked another 5m backward, she would be back where she started.  The total distance she walked would be 20m, and her displacement would be zero !

Answer 2

The Answer Is B)
