Calculating Tension in a Pulley System at an Angle

[mncyapntsi]

Homework Statement

A 1.7kg book B2 is connected by a rope and pulley to a 6.3kg book B1.
We neglect friction.
B2 is on a horizontal surface, and B1 is on a 36.1º slope.
If the force pulling B1 is 28.2N what is the tension between the two books?

Relevant Equations

T=gm

Hi!
I really can't figure this one out...
I have a = (F-cos(36.1)g) = a and from that I get T = mB1 a = 6.3 (20.3736) = 128 N.
Could someone please help?
Thanks!

You need two equations that you get by drawing two free-body diagrams, one for each block. Is the slope above or below the horizontal? Is the pulling force parallel to the surface on which B2 slides? Please post a diagram.

Where is the pulley? Please show a picture of the complete setup as was given to you.

Thank you for the drawing. There is tension T acting on B2 in a direction opposite to F, no? Ideal pulleys change the direction of the force but not its magnitude. Also, check the components of the weight in your equation for B2.
