Logs of masses and
are connected by a rope which is passed over a light pulley as shown in figure 1 below.
The angles of the inclined planes with respect to the horizontal are and
. The log with mass
is
lower than the log with mass
. After the logs move for 3 seconds, they are both at the same height. The coefficient of friction between the logs and the plane is
. What is the ratio of the mass
to that of
?
