Questions
A rigid ball of mass strikes a rigid wall at and gets reflected without loss of speed as shown in the figure. The value of impulse imparted by the wall on the ball will be
detailed solution
Correct option is A
As we know Impulse = Change in momentum. Now along the wall there is no change momentum. The change in momentum perpendicular to the wall is mvCos600-(-mvCos600) =2mvCos600=mvTalk to our academic expert!
