A particle P with speed 140 m s–1begins to decelerate uniformly at a certain instant while another particle Q starts from rest 6 s later and accelerates uniformly. When the second particle Q has travelled 125 m, both particles have a speed of 25 m s–1.i)Show the motion of both on the same speed-time curve. ii)How many seconds after the commencement of deceleration does the first particle P come to rest?
