हिन्दीRefer to the given figure showing two collisions of a ball with a wall. In case (b), the angle made by the path of the ball with the normal is \( 30^\circ \). What is the y-component of the impulse delivered to the ball in case (b)?
Correct answer · Option 1
\( 0 \)
Explanation
Initial y-momentum is \( -mu \sin 30^\circ \) and final y-momentum is \( -mu \sin 30^\circ \). The change in y-component of momentum is zero, hence y-component of impulse is 0.
