Question

If you run east for 38m, stop suddenly, run another 27m east, then you run west for 47

m, what is your total displacement?
how to answer: #m, direction

Answer 1

Total Displacement = -18m

Step-by-step explanation:

Given

East Movement = 38m and 27m

West Movement = 47m

Required

Determine the total displacement

To answer this, we consider east as negative direction and the west as positive (using logics of number line).

Total Displacement = East Movement + West Movement

Total Displacement = -38m - 27m + 47m

Total Displacement = -18m

Hence, the total displacement is 18m towards East
