Homework Statement
Masses m1 and m2 are attached via a light string and pulley on an inclined plane as shown above. m1 has a value of 12 kg and moves down the plane at a constant velocity of 0.9 m/sec. The plane is tilted upwards at an angle of Θ = 26 °. The coefficient of static friction between m1 and the plane is μs = 0.24 and the coefficient of kinetic friction is μk = 0.19.

What is the mass of m2?
Homework Equations
F = ma
f = uk(m1)g
The Attempt at a Solution
y1: m1sin(theta) - T - f = m1a
x1: N - mgcos(theta) = m1a
y2: T -m2g = m2a
Plugging in the numbers into y1 and then I set it equal to T. I then put that equation into y2 and I got 8.5kg for m2, and apparently this is incorrect. Any ideas?
Is my free body diagram correct? Thanks!
