Question : 31 of 100

Marks: +1, -0

The velocity-time graph of motion of two cars A and B is shown in the figure Choose the correct statement.

Accelerations of two cars are equal to each other at time $t=t_0$
Accelerations of two cars are equal to each other at an instant greater than $t_0$
Accelerations of two cars are equal to each other at an instant earlier than $t_0$
At no instant in the interval $0 ≤ t ≤ t_0$ , the two accelerations are equal.

Solution:

Slope of car A is constant and slope of car B will be same between origin

t_0

Hence, accelerations of two cars are equal to each other at an instant earlier than to.
