A car starts from rest from origin O and continues to move till point C as shown in the graph. Select the correct statement about the motion of car as shown in the graph.

Question

A car starts from rest from origin O and continues to move till point C as shown in the graph. Select the correct statement about the motion of car as shown in the graph. (A) Part A B represents uniform motion (B) At instant time t=t2, brakes must have been applied (C) The car stops at t=t3 (D) All of the above

Here, A B represents uniform motion of a car as x-t graph from t1 to t2 varies linearly. At t=t2 brakes must have been applied such that it stops at t=t3. After which the x-t graph becomes parallel to time axis. Thus, all given statements are correct.

Q. A car starts from rest from origin $O$ and continues to move till point $C$ as shown in the graph. Select the correct statement about the motion of car as shown in the graph.

Part $A B$ represents uniform motion

At instant time $t = t_{2}$ , brakes must have been applied

The car stops at $t = t_{3}$

All of the above

Here, $A B$ represents uniform motion of a car as $x - t$ graph from $t_{1}$ to $t_{2}$ varies linearly.
At $t = t_{2}$ brakes must have been applied such that it stops at $t = t_{3}$ .
After which the $x - t$ graph becomes parallel to time axis. Thus, all given statements are correct.

Q. A car starts from rest from origin O and continues to move till point C as shown in the graph. Select the correct statement about the motion of car as shown in the graph.

Part AB represents uniform motion

At instant time t=t2​, brakes must have been applied

The car stops at t=t3​
