Chapter 5, Problem 20P
(II) Two blocks made of different materials connected together by a thin cord, slide down a plane ramp inclined at an angle θ to the horizontal as shown in Fig. 5–34 (block B is above block A). The masses of the blocks are mA and mB, and the coefficients of friction are µA and µB. If mA = mB = 5.0 kg, and µA = 0.20 and µB = 0.30, determine (a) the acceleration of the blocks and (b) the tension in the cord, for an angle θ = 32°.

tion are ua and µr. If ma = mß = 5.0 kg, and

The radius of the circle is R. No sand is to spill onto the surrounding
area; see Fig. Show that the greatest volume of sand that can be stored
in this manner is mu,R 3/3 .where us is the coefficient of static
friction of sand on sand. (The volume of a cone is Ah/3, where A is
