Momentum and Newton's Laws of Motion problem 27

Logs of masses and are connected by a rope which is passed over a light pulley as shown in figure 1 below.

Figure 1: Connected logs on slopes .

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 ?
