Calculate Tension in String: m1=4.50 kg, m2=7.50 kg, a=1.4 m/s^2

[itsmyflow]

Homework Statement

Two blocks of mass m1 = 4.50 kg and m2 = 7.50 kg are connected by a massless string that passes over a frictionless pulley.The inclines are frictionless.

the magnitude of acceleration of each block is 1.4 m/s^2


Find the tension in the string.
?_?
may someone help me start this problem

 

[DorianG]

Start by drawing a free-body diagram for each block.
Identify the forces and directions of each force on blocks 1 and 2 separately.
Then do you know how to find the tension?

yeah i tried that. thanks
i figured out the problem

sum of the force = Tension- M G sin 35 = M A
