Momentum and Impulse Problem with Bouncing (1D & with Angles)

*CORRECTION*
at 5:55 the Px=4.33 kgm/s, which then changes the answer at 8:18 to -8.66 kgm/s
In this video, 2 bouncing scenarios will be analyzed. A one-dimensional collision with a wall, where the force is solved for using momentum and impulse concepts/calculations. The second is a 2-D collision problem, where a ball bounces off a wall at an angle, so the momentum is broken up into components to solve for an impulse.

5 kgm/s × cos 30 = 4.33 kgm/s = P in x- direction
Change in P = - 4.33 - 4.33 = - 8.66 kgm/s

You're right! Thanks for the correction, I jumped to the answer too quickly and wrote two 8.66's instead of 4.33! I'll make a note in the video description.

Ok there's a note in the description now, thanks again for the correction 👍🏼
