A particle moves along a straight line. The fixed point O lies on this line. The displacement of the particle from O at time t t\,t seconds, t≥0t \geq 0t≥0, is s s\,s metres, where
s=t3−5t2−8t+3 s = t^3 - 5t^2 - 8t + 3 s=t3−5t2−8t+3Find the value of t t\,t for which the particle is instantaneously at rest.
