Homework Statement
The three blocks are attached via a massless, frictionless pulley system, as
shown. The frictionless plane is inclined at an angle = 60 degrees. When released
from rest, the 20kg block will start to slide down the plane. Find the tension in the
string.
The image is attached.
Homework Equations
Fnet = ma
The Attempt at a Solution
For the 20 kg block I got, ma = mgsinθ - T
2kg block- ma = 2T - mg
3kg block: ma = 2T - mg
The only problem is that the acceleration of all of the masses is different. How do I find the acceleration of each? Is it a ratio of the tensions, but then the 2kg and 3kg would have the same acceleration which wouldn't make sense?
