A ball moving with a momentum of 15 kgm/s strikes against the wall at an angle of 30 and is reflected with same momentum and angle. Calculate impulse. Basically my problem is that the answer given in the book is 15 square root 3 and my answer is 15 kgm/s

Question

Mohit Dhaka · Answer

Here as per me answer given in book is correct becoz i think you have regarded the angle at an different position This angle of 30°is between normaland path of ball so the impulse generated =2mvcos30°=15square root 3
