sorry for low quality image if you are feeling problem in reading question in image then see this is question
Block A is placed on Block B whoose mass greater than that of A. there is a friction between the blocks, while the ground is smooth. A horizontal force P, is increasing linearly with time, begin act on A The acceleration a1 a2 of A and B respectively are plotted against time choose correct graph.
there is a question as well as options. I think all options are incorrect.
Homework Equations
F=M*a
f=u*N
The Attempt at a Solution
i think curve should straight line for a little time after a specific time. After a time when upper block slipped from lower one after that time acceleration of upper block is zero(no force) so a1 became zero after a time but this is not zero in any figure.
