AI Thread Summary
When a 60N force is applied to the 6kg block, both blocks experience the same acceleration if the force is directed away from the 4kg block. The acceleration can be calculated using Newton's second law, where the total mass being accelerated is the sum of both blocks. Since the floor is frictionless, the force will effectively move both blocks together. Therefore, the acceleration of the 6kg and 4kg blocks will be identical under these conditions. The direction of the applied force is crucial in determining whether the acceleration remains the same for both blocks.

Hello friends
I have a problem.please give me the answer.
Two blocks of masses 6kg and 4kg connected by a rope are resting on frictionless floor.If an instantaneous force of 60N is applied to 6kg block for only a second.Then what is the acceleration of the first and second block.Is the acceleration of first and second box same or different and why?please reply me .[The force applied is parallel to the rope in between 6kg and 4 kg and pulls the blocks]

The acceleration will depend on the direction of the force.
if it is in the direction away from the 4kg block then the acceleration will be the same.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
