Homework Help: SIMPLE and somewhat fun questions I need answers for

  1. Sep 24, 2013 #1
    1. The problem statement, all variables and given/known data

    1. You drop a rock down a well and hear a splash 3 s later. How deep is the well assuming
    that air resistance is negligible and the time needed for sound to travel up the well is also

    2. The acceleration due to gravity on the Moon is about 1/6 that on Earth. If an object is
    dropped near the surface of the Moon, how far does it fall in 10 s?

    3. Charlie walks 1 km to the football stadium in 30 minutes, then sits and watches the game
    for 2 hours, then walks 1 km home in 30 minutes. What was Charlie’s average speed
    while he was gone?

    I hope this is not a bothersome, but if someone can supply me with the answers + a level of reasoning for any or all 3 of these simple physics questions, I will be in debt to you.

    Thanks in advance

    You misunderstand the purpose of this forum, and clearly have not read the rules. As tiny-tim said, you are required to show some attempt on your own part. We do not spoon-feed answers, we try to help you learn how to get answers on your own.

    Yup, I had not read any of the rules of this forum which are perfectly reasonable. I will surely follow the rules in my next thread should I require help again. However, this post need not be responded to any longer since I've worked out the answers myself after much suffering lol. Thanks guys.
