Homework Help: Explain me this concept (Laws of Motion)

  1. Apr 9, 2010 #1
    Two blocks placed one on top of the other are lying on a horizontal smooth surface. The coefficient of friction between the blocks is [tex]\mu[/tex].

    Case 1: Horizontal force F is applied to the lower block (Fig. 14).

    Please help me to find out how they have got those equations. I'm trying to find it from past several hours but couldn't got any hint.​

    Hi snshusat161! :smile:

    (your link isn't working … it's http://www.monbattle.com/1.jpg" [Broken] :wink:)

    You need to do good ol' Newton's second law (F = ma) twice, once for each block.

    What equations do you get? :smile:
