**1. Homework Statement**

For two blocks, connected by a cord and sliding down the incline shown in the figure, describe the motion (a) if [tex]\mu_1 < \mu_2[/tex], and (b) if [tex]\mu_1 > \mu_2[/tex]. (c) Determine a formula for the acceleration of each block and the tension F

_{T}in teh cord in terms of m

_{1}, m

_{2}, and [tex]\theta[/tex]; interpret your results in light of your answers to (a) and (b).

I need help on part c.

I got two equations in three unknowns ([tex]T, a_1, a_2[/tex]), and I don't know what to do:

[tex]m_1 g \sin \theta - F_{fk1} - T = m_1 a_1[/tex]

[tex]T + m_2 g \sin \theta - F_{fk2} = m_2 a_2[/tex]

[tex]F_{fk1} = \mu_1 N_1[/tex]

[tex]F_{fk2} = \mu_2 N_2[/tex]
