Acceleration (a) = dv/dt = 3t2 − 2t
at t = 3 sec
a = 3 × 3 × 3 – 2 × 3 = 21 m/s2
at t = 3 sec
a = 3 × 3 × 3 – 2 × 3 = 21 m/s2

The equation v = t^3 represents the velocity of the particle as a function of time, where v is the velocity in m/s and t is the time in seconds.
This equation indicates that the velocity of the particle increases rapidly with time, as t is raised to the power of 3. As time increases, the velocity of the particle also increases, resulting in an accelerating motion.
It is important to note that this equation only represents the velocity of the particle and does not provide information about the position or acceleration of the particle. To obtain information about the position or acceleration, additional equations or information would be required.
