I'm studying physics but in this question I can't figure out the free body diagram.
$$T-m_3 g = m_3a $$
For $m_2$ along the y-axis:
$$N - (m_2 + m_1)g = 0 $$
But I can't figure out the x-axis forces on $m_2$.
Sorry about this basic question. I have no choice to ask anybody else.
Now, I'm trying to find T equation on $m_3$
@Steeven said $$T = m_2a$$ so when I try to solve it $a=20m/s^2$
It is seems not right.
At the top first equation should be like this. $$m_3g - T = m_3a $$ After that it seems correct.
