negative acceleration could come from the viscous force by the liquid on the bubble?

The forces in their respective components should be balanced out if the system of particles is at equilibrium.

change in momentum - impulse. do you have the answer to this question ?

at t=(t-1) v=u+at hence v = a(t-1) s = ut + 1/2 at^2 s = at(t-1) + 1/2a(t-1)^2 s will be positive

you should try and think what is constant and then try to apply that here. try to equate constant values .

Homework Statement mA=5kg , mB =10kg , coeff of friction is same for static and kinetic friction = 0.15 g=10ms-2 2 blocks a , b are in contact with each other resting against a rigid wall on a horizontal surface. There is fricition acting between the blocks and the surface . A force of...

they mean the amount of impulsive force delivered and in normal units so that people can understand .
