An object is moving horizontally along a straight line. Its position, in metres, after t seconds is described by the position function s(t)=r' - 4r² +t, t20 a) Determine velocity and acceleration functions. b) Determine the velocity and acceleration at t = 2. Is the object speeding up or slowing down at that time? Justify your answer.
