Yes, Peter, there are two ways to solve this problem. One is the one you outlined. But one can also do my way, without regarding the two masses as a unique body, so without need to think about the verse of the acceleration. You just write Newton's 2nd law for both and you have a system of two...
Why not? What do you mean by realise? One can fix the reference system arbitrarily. Then you need to express the coordinate of vectors in this system. If they are unknown, you just use a variable, which at the end can be either positive o negative. So for instance, the acceleration is a vector...
Hi Peter, yes, F2 is 3 times F1, but m2 could be more then 3 times m1, so that the acceleration would be in the direction of F1 and not the direction of F2. A force does not equate the acceleration, but there is a mass factor (this is Newton's 2nd law). I do not think we need to guess right to...
Homework Statement
Two bodies with masses m1 and m2 are connected by a massless thread that supports a maximum force |Ft|max . On mass m1 the force F1 = -β t x and on mass m2 the force F2 = 3 β t x (t: time, β: constant) acts. The motion is frictionless.
