Read the scenario.
A cyclist starts at a position of 0 m and takes 3 s to move east to a position of +8 m. He then cycles west to a position of +5 m which takes an additional 2 s.
What is the cyclist’s displacement?
-5 m
- 8 m
+5 m
+11 m
He then cycles west to a position of +5 m
clearly, +5
the rest is just smokescreen
To find the cyclist's displacement, we need to calculate the difference between the cyclist's final position and initial position. In this case, the final position is +5 m and the initial position is 0 m.
The cyclist traveled east for 8 meters and then traveled west for 3 meters, so the displacement is the net result of these two movements. The displacement should take into account the direction and the magnitude of the movement.
To calculate the displacement, we subtract the initial position from the final position:
Displacement = Final Position - Initial Position
Displacement = +5 m - 0 m
Displacement = +5 m
So, the cyclist's displacement is +5 m.
