Please Note: It may not always be possible to include the necessary special characters, superscripts, subscripts, etc. in e-mail responses to this group of exercises. We suggest that you discuss this matter with your professor/class and decide upon a system for indicating such characters. You may cut/paste some characters and/or Greek letters from Microsoft Word, using the Insert menu. Alternatively, we suggest that you agree upon abbreviations for or spell out symbols, Greek letters, or characters and indicate superscripts and subscripts by using "sup", "sub", or up/down carats.

Consider two masses located on the x-axis as follows:

22			Force m1 exerts on m2 Need a Hint?
23			Force m2 exerts on m1 Need a Hint?
24			If m1 were to double in mass, the new force m1 exerts on m2 Need a Hint?
25			If m2 were to triple in mass, the new force m1 exerts on m2 Need a Hint?
26			If m2 is moved to x = 6.00 m, the new force m1 exerts on m2 Need a Hint?
27			If m1 were to double in mass, m2 were to triple in mass, and m2 was moved to x = 6.00 m, the new force m1 exerts on m2 Need a Hint?
28			Location on the x-axis where we could place m3 = 3.00 kg and have it feel no net force Need a Hint?
