NEET Physics Speed & Velocity Assertion Reason Question
Assertion (A): The stopping distance of a vehicle increases with the square of its initial speed.
Reason (R): The stopping distance formula includes the initial velocity squared term.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
The stopping distance formula v^2 = v_0^2 + 2ax shows that stopping distance is proportional to the square of the initial velocity, which explains the assertion.
