The question as text
A particle P moves in a straight line starting from a point O and comes to rest 14 s later. At time t s after leaving O, the velocity v m s−1 of P is given by v = pt2 −qt 0 ≤t ≤6, v = 63 −4.5t 6 ≤t ≤14, where p and q are positive constants. The acceleration of P is zero when t = 2.
