A particle moves along a line so that its position at any time 1 2 0 is given by the function s(1) = -167 + 60r + 100, where's is measured in feet and / is measured in seconds. (a) Find the displacement during the first 5 seconds, (b) Find the average velocity during the first 5 seconds. (c) Find the instantaneous velocity when / - 5. d) Find the acceleration of the particle when / = 5. (e) At what value or values of f does the particle change direction
