These videos are 40 times more valuable than lecture, the text book, and so much cheeper and efficient than a private tutor.

This was a lifesaver!! I honestly was so lost on many of these chapters in AP Physics and the way you walked through how to get the answer was extremely helpful. Thank you so much for offering these videos explaining the steps to get the correct answer. After taking the AP test, I found that I earned a 3! Without your help, I would have probably gotten much lower. Thank you for helping me avoid many tearful nights of confusion and frustration! I would highly recommend your website to anyone taking physics, because you broke down the tough problems step by step. Thank you again and I hope you gain more business in the future!

This is a wonderful service. He goes over all of the problems of each chapter and gives both the answer in a quick text form (good if you are on your cell in the library etc) AND has a video which explains the entire problem if you want a detailed explanation. It's like having a tutor, which is a huge help! The cost is reasonable especially for the instruction you get-and WAY cheaper than the ripoff answer guides that the textbook business wants to force you to buy. Give this a month try and i promise you will want to keep using it. Huge help.

Why not start (a) with Torque equation 245Nd=735N(9-d) and d= distance between child and pivot. Then solve for d is easy. Pivot is 6.75 m away from child. That approach is simpler than what is shown.

Hi joseotilio25, please see my answer to your question about why the trains had the same elapsed time here: https://www.giancolianswers.com/giancoli-physics-7th-edition-solutions/c.... Instead of trains, this question has Sally and Mary, but otherwise it's the same idea.
Good luck!
