The equation of one dimensional motion of particle is described in column I. At t = 0, particle is at origin and at rest. Match the column I with the statements in column II.
Column-I | Column-II |
(i) x = (3t2 + 2)m | [A] velocity of particle at t = 1 s is 8 m/s |
(ii) v = 8t m/s Acceleration | [B] particle moves with uniform |
(iii) a = 16 t acceleration | [C] particle moves with variable |
(iv) v = 6t – 3t2 | [D] particle will change its direction some time |
