Two masses are connected by a string over an ideal pulley as shown. The coefficient of kinetic friction between m1 and the table surface is \mu. Find an expression for their common speed after the blocks have moved a distance L. You can assume that you know: m1, m2, L, and \mu. (i.e. It's ok for those variables and any known constants to appear in your answer.) Show all work. Diagram here: http://imgur.com/CUMJmPZ

Answer #1

the driving force is m2 g
less the friction force which is m1 g ??
These are constant so there is constant acceleration. You are permitted L but not t.
So you need to use energy. 1/2 (m1 + m2) v^2 = F * L = g(m2 - m1?? )

a = g*[1 - (1+
