A car travels 20. meters east in 1.0 second. The displacement of the car at the end of this 1.0-second interval is
- A 20. m/s
- B 20. m
- C 20. m east
- D 20. m/s east
That's Correct!
It's Wrong!
The displacement of the car at the end of the 1.0-second interval is 20 meters east. Displacement refers to the change in position of an object, taking into account both the distance traveled and the direction. In this case, the car travels 20 meters in the east direction, so the displacement is 20 meters east. The units for displacement are distance units (meters) and the direction is indicated by the word "east".
