A particle moving uniformly along the x axis is located at 11.3 m at 0.588s and at 3.38 m at 4.67s. Find the displacement during this time intervals.

The displacement is

(position at the end of the time interval)

minus

(position at the beginning of the time interval).

Displacement = (3.38m - 11.3m) = - 7.92 meters.

The time labels aren't needed to calculate displacement.

They're only there to confuse us and to see whether we

really know what we're doing.
