Homework Help: physics

Posted by lissa on Friday, March 2, 2012 at 1:03pm.

A block of mass m1 = 21.3 kg is at rest on a plane inclined by θ = 30.00 degrees. It is connected via a rope and pulley system to another mass m2 = 24.5 kg, as shown. The coefficients of static and kinetic friction between block 1 and the inclined plane are μs = 0.113 and μk = 0.09, respectively. If the system is released from rest, what is the displacement of block 2 in vertical direction after 1.41 s? Use positive numbers for upward direction and negative numbers for downward.
