SUMMARY
The discussion centers on the calculation of particle velocity and acceleration from the equation $\int v(t) dt = 3{t}^{2}-{t}^{2}+C$. Participants clarify that "instantaneous rest" refers to moments when the particle's velocity is zero, specifically at $t=0$ and $t=2$. The correct acceleration at $t=2$ is determined to be $4 \ m/s^2$, while the confusion around the value of $-6 \ m/s^2$ is resolved by emphasizing that acceleration is derived from the velocity function, not its integral.
