@Granger ,
You need to have some patience and little more decency if you wish to interact on this forum .
You are wrong on several accounts .
1) You said , TSny is vague . I don't think so . You asked for a hint . He gave you a hint . You might not have found that hint helpful . In that case...
You are quite distracted by the acceleration of the massless pulley :cool: .
The original problem asks you to calculate accelerations of the two masses , not the acceleration of the pulley :mad:. You do not need acceleration of the pulley to determine acceleration of the two masses .It's the...
No . F is not given to you :oldgrumpy: . You are only given acceleration of the pulley .Please read the question again in post#15 .
Let us discuss this part later after you have completed the original question .
Think about the three values of forces given to you .
Yes . But remember all what we have discussed so far is under the assumption that sufficient force is acting on the pulley such that both the masses are in air .
Go back and read the question again . You have been given three forces . Now think , why are three different forces given to you .
OK .
Instead of force F acting on the pulley consider the pulley accelerating upwards with acceleration a = 10ms-2 and same masses as given in the OP , find the acceleration of the two masses ?
Yes .
Now , from the constraint relation you can find the acceleration of the pulley :smile: .
But since you are too eager to work from an accelerating frame ,would you like me to give you an exercise ?
No .
Fictitious force is given by mass of the object times acceleration of the frame of reference , acting in the direction opposite to the accelerating frame .
