A particle P moves in a straight line such that, t s after leaving a point O, its velocity v ms^-1 is given by v=36t - 3t^2 for
t>_ 0 1) find the value of t when the velocity of P stops increasing 2)find the value of t when P comes to instaneous rest 3) find the distance of P from O when P is at instaneous rest 4) find the speed of P when P is again at O
