The acceleration of a particle is given by a = t3 – 3t2 + 5 m/s2 where the time “t” is in seconds.
If the Velocity of the particle at t = 1 second is 6.25 m/s and displacement is 8.8m, the Velocity
and displacement at t = 2 seconds is :
(A) 8 m/sec, 16.1m (B) 8.5 m/sec, 16.5m
(C) 9 m/sec, 16.1m (D) 16.4 m/sec, 8m
