Two blocks are connected by a string over a frictionless, massless pulley such that one is resting on an inclined plane and the other is hanging over the top edge of the plane. the hanging block has a mass of 16 kg and the one on the plane has a mass of 8 kg. the coefficient of kinetic friction between the block and the inclined plane is 0.23. the blocks are released from rest.

Edit: The incline is at an angle of 37 degrees.

a. what is the acceleration of the blocks?

b. what is the tension in the string connecting the blocks?

2. Relevant equations

Ffr=Coefficient x Fn

A= Fnet / Mass

3. The attempt at a solution

I solved for the Fgx and the Fgy using cos and sine. I got Fgx= 47.18 N, and for Fgy= 62.6 N. I solved for Force of friction using equations above and got 14.4 N. Also I found the Fg for the 16 kg block to be 156.8. So I found Fnet of the whole system = 95.22. Divided by mass of 24 gives an acceleration of 4 m/s2 (I think ?)

For tension, so far I have figured the tension of the string of just the 16 kg block to be 92.8 N ? Not sure where to go now..
