After waiting for certain time interval police car starts chasing thief with constant acceleration and catches the thief: Graph (1) Graph (2), (1) Graph (1) represents displacement vs tima graph for police car. (2) Graph (2) represents displacement vs time graph for thief. (3) Displacement of police car and thief are pe equal from check point. (4) Average velocity of police car and thief is pot equal in time interval t=t, to T till thief is caught. 28, Velocity of a particle varies with time a. v =t² -t-2. Average speed of the particle in time interval from t = 0 to t = 4 sec is : 4 (1) m/s (2) 2 m/s (3)3 m/s (4) 5 m/s 3 Paragraph for question nos. 29 and 30 The next TWO questions will refer to the following situation.
