[i]A particle moves along a straight line and passes a fixed point O with an initial 8 [math]ms^{-1}[/math] velocity. Its acceleration, a [math]ms^{-2}[/math], at time t seconds after passing O is given by [math]a=10-6t[/math], find[/i][br][br][i](a) the maximum displacement of the particle,[/i]

([i]b) the distance traveled by the particle in the 5th second[/i]
