Homework Statement
m1 and m2 are two blocks tied with a rope with a pulley inbetween, like those in this picture
http://labella.altervista.org/images/mechanicsoftwopoint_2.png
there are no frictions.
find: the linear acceleration of the blocks and the tension of the rope on both m1 and m2.
The Attempt at a Solution
I'd say it is:
## m_2 \cdot g = I \alpha + m_1 \cdot a + m_2 \cdot a## with ##a= \alpha \cdot R_0## being ##R_0## the radius of the pulley
## m_2 \cdot g= m_1 \cdot a + I \frac{a}{R_0}+m_2 \cdot a## so
##a=\frac{m_2 \cdot g}{mb + \frac{I}{R_0}}##
and then the tension of the rope on m1 is simply
T=a*m1
while the tension on m2 is
T=m2*g+m2*a
Is it correct? If not, why?
Thank you for checking :)
