Newton's second law 3 pulley problem.

[travisdass123]

There is no friction and the strings are massless. Find Tension and acceleration.

3. The Attempt at a Solution

1. +T-m1g = m1a
2. m2g-2t= m2a
3. +T - m3g =m3a
4. 2a2 = a1+a3

g(-m1+m2-m3) + 2a2 = (m1 + m2 + m3)a + a1 + a2

-29.4 + 2a2 =11a +a1+ a2

There is no friction and the strings are massless. Find T1 T2 T3 and acceleration.

If there is no friction, then the tension in the string connecting the 2kg and 5kg masses should be constant throughout.
