A:
Block B, with mass
5.00 kg, rests on block A, with
mass 8.00 kg, which in turn is on
a horizontal tabletop (Fig..
There is no friction between block
A and the tabletop, but the coefficient
of static friction between
blocks A and B is 0.750. A light
string attached to block A passes
over a frictionless, massless pulley,
and block C is suspended from the other end of the string. What is
the largest mass that block C can have so that blocks A and B still slide
together when the system is released from rest?
