Physics 4.7 Friction & Forces at Angles (4 of 8) Horizontal Surface with 2 Blocks

Visit http://ilectureonline.com for more math and science lectures! In this video I will find a) maximum force=? pushed at 30 degrees on to a 3kg on top of a 5kg box on a horizontal surface with frictions of 0.4 and 0.2, respectively, before the top box starts moving; and b) a=? of the 2 boxes.
