Impulse and Deformation in Collision – Rankers Physics

Collision: Practice Problem & Solution

Assertion (A): When one object collides with another object, the impulse during deformation and reformation will be in same direction on one particular object. Reason (R): Due to deformation impulse the objects first deform and due to the same reformation impulse, they again try to regain its original shape.  
(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)
(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(3) (A) is true but (R) is false
(4) Both (A) and (R) are false

Solution Explained:

To solve this problem, we apply the core principles of Collision. Understanding the underlying formula is key to arriving at the correct answer below:

Assertion (A): During collision, the impulses during the deformation phase and reformation phase on a particular object act in opposite directions. So, (A) is false.

Reason (R): The deformation impulse and reformation impulse are distinct. They are not the 'same' impulse. So, (R) is false. Since both (A) and (R) are false, option (4) is correct.
