The position of a particle moving along 12t2 – 2t°, where r is in meters and t is in an r-axis is given by x = seconds. i Determine the acceleration of the particle at t = 3.0 s. ii What are the maximum positive coordinate reached by the parti- cle and the acceleration of the particle at that instant? Answer: i) a(t = 3 s) = -12 m/s? ii) r(t = 4 s) 4 s) = -24 m/s? 64 m, a(t %3D The position of a particle moving along 12t2 – 2t°, where r is in meters and t is in an r-axis is given by x = seconds. i Determine the acceleration of the particle at t = 3.0 s. ii What are the maximum positive coordinate reached by the parti- cle and the acceleration of the particle at that instant?
