EXAMPLE 5 Studying Particle Motion A particle moves along a line so that its position at any time tz 0 is given by the func- tion s(t) = r – 41 + 3, where s is measured in meters and t is measured in seconds. (a) Find the displacement of the particle during the first 2 seconds. (b) Find the average velocity of the particle during the first 4 seconds. (e) Find the instantaneous velocity of the particle when t = 4. (d) Find the acceleration of the particle when 1 = 4. (e) Describe the motion of the particle. At what values of t does the particle change directions? (1) Use parametric graphing to view the motion of the particle on the horizontal line y = 2.
