A particle moves along a straight line from a fixed point O for t seconds with an initial velocity of 8ms[sup]-1[/sup]. The acceleration, a ms[sup]-2[/sup], of the particle t seconds after leaving O is given by [math]a=6=6t[/math]. Calculate[br][Assume motion to the right is positive]
(a) the velocity, in ms[sup]-1[/sup], of the particle when t=2,
(b) the displacement, in m, of the particle from O when t=5.[br]
