A particle P P\,P travels along a straight line through a point O O\,O so that at time t t\,t s after passing through O O\,O its displacement from O O\,O is x x\,x m, where x=t3+at2+btx=t^3+at^2+btx=t3+at2+bt
Given that the initial velocity of P P\,P is 74 m s-1, find the value of bbb.
Given that P P\,P has zero acceleration when t=6t=6t=6, find the value of aaa.
