Calculating the vector change in momentum for a bouncing ball.

A 50 g ball is moving down towards the ground with a speed of 3.2 m/s at a 60 degree angle. After colliding with the ground, it moves up with a speed of 2.8 m/s at a 70 degree angle. What is the change in momentum?

I love how you take on these different problems, keep them coming, going to start at university very soon, physics and astrophysics :)

My school / college (AS Level) has taught this incorrectly. That is why I did not have any idea what they were talking about. Thank you for the tutorial.

Glad it helped!

Just curious, how did they explain it that was wrong?

[@Scratchfan321]

@@DotPhysics They were directly adding the horizontal velocity with the vertical velocity to find the overall velocity even though they're at right angles. In the video the (X, Y) parts of the velocity are treated separately.
