Three boxes of masses 25 15 and 30 kg are connected:
link to my picture:
The tension on the connecting strings are T1 and T2. The assembly is realeased from rest at t = 0. There is no friction between the box and table.
a) find acceleration of the boxes
b) find T1
c) find T2
d) If there is friction between the box and the table and the coef. of friction is .15, How much is the acceleration of the boxes?
F = ma
W = mg
F = friction x normal force
The Attempt at a Solution
i feel like i'm overthinking the problem. Is it right to add all of the vectors going in the same direction to each other? Maybe I'm under thinking the problem. I never got clarification on what's what.
I just need someone to explain the problem in simpler terms. I've already asked alot of people (tutor, prof, friends) this is my last resort sooo...
I hope someone can explain the mechanics of the problem
The major thing i know to do is that f = ma can be applied to two masses at the same time by adding the masses...and that's all. my answers
