Thanks for your help.

So is the diagram just a slope and no circular motion.

That should be mg sin theta sorry.

Does the centripetal force become t-mg as it is the net force.

I don't know where to start with this as I can't visualise a diagram for it. Any help would be appreciated.

OK I get it now, thank you for your help.

Yes but I don't understand how the top block remains at rest but is accelerating at the same time

In the problem you apply a force to the bottom block with the lighter block on top and both accelerate.

Acceleration is the rate of change if velocity with time but I think the velocity is 0 so there is no acceleration.

I know the answer but don't understand the concept. The solution says the accelerations are the same but if the top block is at rest how can it be accelerating. I know you can view both blocks as the same system but can you not study them independently. Any help would be appreciated.

I am studying introductory physics in my 1st year at college.
