हिन्दीA rigid ball of mass m strikes a rigid wall at \( 60^\circ \) and gets reflected without loss of speed as shown in the figure below. The value of impulse imparted by the wall on the ball will be
Correct answer · Option 2
\( \text{mV} \)
Explanation
Impulse \( J = \Delta P = 2mv \cos\theta = 2mv \cos(60^\circ) = 2mv (\frac{1}{2}) = mv \).
