For the two blocks initially at rest as shown, under constant external forces their acceleration are, `a_(1)=5m//s^(2)rarr,a_(2)=2m//s^(2)larr`. Which of the following is correct ?

Block A and C start from rest and move to the right with acceleration a_(A)=12t m//s^(2) and a_(C)=3m//s^(2) Here t is in seconds. The time when block B attain comes to rest is:

A block is placed over a plank. The coefficient of friction between the block and the plank is mu= 0.2. Initially both are at rest, suddenly the plank starts moving with acceleration a_(0) = 4m//s^(2). The displacement of the block in 1 is (g=10m//s^(2))

A mass m of volume V=10cm^(2) is tied with a string to the base of a container filled with a liquid of density (P_(l)=10^(3)kg//m^(3)) as shown in the figure. The container is then accelerated with acceleration (a_(x)=9m//s^(2)) and (a_(y)=2m//s^(2)) a shown in the figure. [ g=10((m)/(s^(2))) acceleration due to gravity] the net buoyancy force acting on the mass is
