Figure ahead represents the displacement-time sketch of motion of two cars A and B.
Find —
(i) The distance by which the car B was initially ahead of car A.
(ii) The velocities of car A and car B
(iii) The time in which car A catches car B
(iv) The distance from start when the car A will catch the car B

Figure shows the velocity-time graph for the motion of a body. Use it to find the displacement of the body at t = 1 s, 2 s, 3 s and 4 s, then draw the displacement-time graph for it on figure (b).
Figure shows the displacement of a body at different times.
(a) Calculate the velocity of the body as it moves for time interval
(i) 0 to 5 s,
(ii) 5 s to 7 s and
(iii) 7 s to 9 s.
(b) Calculate the average velocity during the time interval 5 s to 9 s.
[ Hint — From 5 s to 9 s, displacement = 7 m - 3 m = 4 m ]
