Homework Statement
It is a Matching Type Problem(a single entry in a column can be matched with more than one in the other column):-
A block is projected with an initial velocity ##v_{\text{Block}}## on a long conveyor belt moving with velocity ##v_{\text{Belt}}##(at that instant) having constant acceleration ##a_{\text{Belt}}##. Mark the correct option regarding friction after long time (coefficient of friction between the block and belt##=\mu##). If:
Homework Equations
The Attempt at a Solution
In the first entry in Column-1 it is mentioned that the conveyor belt has no acceleration, I was really confused about it that whether the conveyor belt is allowed to have an acceleration greater than 0, because if it is not so then how could the friction act to accelerate the conveyor belt and deaccelerate the Block as the conveyor belt is constrained to move with zero acceleration.
In all the entries what is troubling me is that whether the conveyor belts are constrained to move with the acceleration indicated only (or in that range only) or can they be acted upon by the friction to change their acceleration for sometime in an attempt to make the block and the conveyor belt move together.
