(a) Two particles P and Q move in a straight line AB. The particle P starts from A in the direction AB with velocity u and acceleration fi and at the same time the particle Q starts from B in the direction BA with velocity u2 and acceleration f2. If they pass one another one another at the middle of AB and arrive a the other ends of AB with equal velocitics, prove that (Hi + 42)(Si - 2) = 8(Si42- SaH). Also prove that if they have the same velocity at the middle of AB, then AB fi- f
