Assertion : Kinematic equations are exact and are always correct.
Reason : The definitions of instantaneous velocity and acceleration are true only for motion in which the magnitude and direction of acceleration are constant during the course of motion.

A

If both assertion and reason are trure and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanations of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason is false

Text Solution

Verified by Experts

The correct Answer is:
(d)
The defintions of instantaneous velocity and acceleration are exact and are always correct while the kinematics equations are true only for motion in which the magnitude and the direction of acceleration are constant during the course of motion.
