## Homework Statement

## Homework Equations

f = ma

## The Attempt at a Solution

t

_{1}tension in string connecting M

_{c}

t

_{1}tension in string connecting M

_{a}and M

_{b}

##

m_c:\\

m_c g - T_1 = m_c a_c\\

##

i considered pseudo for acting on masses b and a from a non inertial frame of reference

hence in that frame of reference mass b will go down with a

_{observed}and mass a will go up with a

_{observed}

##

m_a,m_b:\\

a_{observed} = \frac{(m_b - m_a)a_c}{m_b + m_a}\\

a_b = a_c - \frac{(m_b - m_a)a_c}{m_b + m_a}\\

a_a = a_c + \frac{(m_b - m_a)a_c}{m_b + m_a}\\

T_2 = m_a a_a = m_b a_b\\

2 T_2 = T_1\\

is this correct i have feeling something has gone wrong

but how could i solve without pseudo forces i feel very uncomfortable having to switch frames of references
