A particle moves along the x axis. Its position varies with time according to the expression x ! #4t % 2t 2 where x is in meters and t is in seconds. 3 The position–time graphfor this motion is shown in Figure 2.4. Note that the particle moves in the negative x direction for the first second ofmotion, is momentarily at rest at the moment t ! 1 s, and moves in the positive x direction at times t & 1 s. (A) Determine the displacement of the particle in the time intervals 0 to to 1 s and 1 s to 3 s.
