Apply Newton's second law to all three bodies in succession.

anonymous · Answer

ok Newton second law is F=ma  so what i did was t1= (1.16)(9.8)= 11.368

anonymous · Answer

then from here im kind of stuck.

anonymous · Answer

am i on the right track so far?

vincent-lyon.fr · Answer

Use letters and not numbers.
Write all three equations with tensions T1 and T2, then simplify.

anonymous · Answer

im still kind of stuck what do you mean?

You must review Atwood machine problems. Your problem is similar but more complicated. This video will help you understand how it works: http://www.youtube.com/watch?v=a0KVxh8iPP4
