Like.
Took me a while to get that last step. Need to consider infinitesimal changes, yes? If the magnitude of the velocity change is dv then... -

Yes. I think that's it! :smile: The two friction forces are represented by f. ##\vec W_1## is the velocity of the block relative to...

Kkekpillangok replied to the thread Block drifts off between two moving planes through friction.Can we explain this from the fact that, at each instant, there are acceleration vectors of equal magnitude along the directions of the...

Kkekpillangok replied to the thread Block drifts off between two moving planes through friction.The two forces on the block are ##\vec{f }_{1 } ## and ##\vec{f }_{2 } ##. The net force in the x-direction, therefore, is ## f _{1...

Kkekpillangok replied to the thread Block drifts off between two moving planes through friction.I'm a bit puzzled. If the particle starts from rest, it seems to me that, at each instant, the acceleration and velocity vectors should...

Kkekpillangok replied to the thread Block drifts off between two moving planes through friction.Thanks for replying! I found the following expressions for the derivatives: ##\frac{\, \mathrm{d } \, v _{1 } \, }{\, \mathrm{d } \, t...

Kkekpillangok posted the thread Block drifts off between two moving planes through friction in Introductory Physics Homework Help.Here's what I've tried. ##\vec{v } ## is the velocity of the brick after it has stopped changing. I've been able to conclude that this...
