Question

Two cars A and B start from a same point at same instant of time and move in same direction. The variation of their respective velocities with time is indicated in the graph
as shown in the figure. The time after their motion starts, when the cars cross each other is
Velocity (m/s)
Car A
2+
Car B
1+
2
-6 -5 -4 -3 -2 -
Time(s)
0 4 5
08 s
0 5 s
0 10 s​

Answer 1

Slope of the velocity-time graph gives the acceleration of the body. Since, at the instant earlier than to, slope of car A and car B is same. Thus accelerations of two cars are equal to each other at an instant earlier than t
