- A 70.0-kg ice hockey goalie, originally at rest, catches a 0.150-kg hockey puck slapped at him at a velocity of 35.0 m/ s. Suppose the goalie and the ice puck have an elastic collision and the puck is reflected back in the direction from which it came. What would their final velocities be in this case?

Hi all - Here's the link mentioned in the video: ruclips.net/video/ltg_Uut3D8E/видео.html
For people getting wrong answers on Expert TA: Follow the exact steps in this video but the final answer should be negative. Thanks again Glaser Tutoring, you guys are saving so many people's grades!
Thank you for the update. I am so glad that you found this channel and that it is helping you in your Physics class. Keep up the great work and thank you for being a part of this community! 😀
Now ik what people mean when they say you should take algebra 2 before taking ap physics 1. Thx again your a life saver
haha yeah, it would be hard without Algebra 2! 😂
In Expert TA the answer for the final velocity for the goalie is positive and the puck's velocity is negative. I am not sure if that is an error on their part or how the equation was set up.
Hi Ashley, the signs of the final velocities are relative to how the problem was set up initially. Expert TA must have assumed the puck was initially moving to the right where I assumed it's moving to the left. The problem does not state the direction and therefore it is left up individual interpretation.
Please put link of video prior to this in the description so people can check where that equation came from
Here it is! ruclips.net/video/ltg_Uut3D8E/видео.html
Lol! Poor UPS driver/window. :P
😂😂😂
wait where do you get the second energy conservation formula? I see other people solve it using the (1/2)mv^2 + (1/2)mv^2 = (1/2)mv^2 + (1/2)mv^2
Please listen carefully beginning at 3:20. I have made a 25-minute video to explain your exact question, which is basically question 8.29 in the OpenStax textbook. All issues should be resolved in that video. Cheers!
Thank you for this!
You got it, Trenton! Keep working hard and help us spread the word in your class! 😀
this was so helpful!! thank you!
You're very welcome, Olivia! Keep studying hard! 😀
I'm looking fro solutions on Chapter 14 questions: conduction. Any chance you've gotten that far?
We have not gotten that far yet, as we are seeing if the channel is viable. Spread the word to help us out!
@@GlaserTutoring You got it, sir! My classmates and I are taking high school physics right now, and we really need all the help we can get. ❤️
Thank you so much!
You're very welcome! Keep up the hard work!
My physics 11 course is working through this, I don't think this is physics 11 material...
