1) I don't know how to do this, but I know there is the force of gravity by the earth in the force diagram..

2) For this one I got the answer

Fx=7.5N [I did 1/2(15N) which equals 7.5 N]

Fy=13N [I took my x component 7.5N and I did 7.5sqrt3=13N]

Did I solve this problem right??

3) How do you write an equation for this diagram?

Can you tell me if I did the Bonus right?

T1cos(60)=T2

T2sin(60)= 3kg

T1sin(60)=3kg

I divided both sides by sin(60) to make T1 by itself so

T1sin(60)/sin(60)=3.464

SO T1=3.464

I took T1=3.464 and plug it into T1cos(60)=T2

3.464cos(60)=T2

T2=1.232

So I don't know if I got that one right??

My answer is T1=3.464 and T2=1.232

Please help me..I really need this. Thank you!
