1. Homework Statement

Two blocks of masses m1 = 3.7 kg and m2 = 3.3 kg are connected by a string as shown in the figure above. The horizontal surface is frictionless. A 15 N force directed at 18 degrees above the horizontal acts on m2.

Determine the acceleration of the blocks and the tension in the string.

## Homework Equations

m1=3.7kg

m2=3.3kg

F= 15N

θ

_{Fo}=18°

F

_{f}=0

## The Attempt at a Solution

W

∑Fx= m⋅a

W

_{m2}= 9.8m/s^2x3.3kg = 32.34N∑Fx= m⋅a

_{x}-F

_{x}+M1 =m⋅a

_{x}

-(cos 18°⋅15N)+M1 = 3.3kg⋅-a

_{x}

I'm kind of stuck after this..
