Block B starts from rest and accelerates as `a_(B)=12tms^(-2)`. Simultaneously another end of the string is pulled with constant acceleration `a_(0)`. If at t = 3s, block A block A comes to rest than then the value of `a_(0)(" in "m s^(-2))` is equal to

Block B starts from rest and accelerates as a_(B)=12tms^(-2) . Simultaneously another end of the string is pulled with constant acceleration a_(0) . If at t = 3s, block A comes to rest than then the value of a_(0)(" in "m s^(-2)) is equal to

A body a starts from rest with an acceleration a_(1) . After 2s, another body B starts from rest with an acceleration a_(2) . If they travel equal distances in the 5^(th) second after the start of A then, the ratio a_(1) :a_(2) is equal to :

An object A starts from rest and moves with acceleration a_(1).Two seconds later,another object 'B' starts from rest and moves with an acceleration a_(2) .If the displacement of A in the 5th second is the same as that of B in the same interval,the ratio of a_(1) to a_(2)is

A starts from rest and moves with acceleration a_(1) . Two seconds later B starts from rest and moves with an acceleration a_(2) . If the displacement of A in the 5^(th) second is the same as that of B in the same interval, the ratio of a_(1) to a_(2) is

Find the acceleration of block B realtive to the ground if the block A moves to the left with an acceleration a_(0) .

If block A starts from rest at t=0 & begins to move towards right with 2 m//s^(2) & simultaneously C moves towards right with constant velocity of 4 m/s. Velocity of block B at t=5 sec. will be:

A body P starts from rest with an acceleration a_(1) . After 2 seconds, another body Q starts from rest with an acceleration a_(2) from the same point. If they travel equal distances in the fifth second after starting of the motion of the P, then the ratio a_(1) : a_(2) is equal to

Blocks P and R starts from rest and moves to the right with acceleration a_(p) = 12t m//s^(2) and a_(R) = 3 m//s^(2) . Here t is in seconds . The time when block Q again comes to rest is

Block A and C starts from rest and move to the right with acceleration a_(A)=12tms^(-2) and a_(C )=3ms^(-2) . Here t is in second. The time when block B again comes to rest is

Block A and C starts from rest and move to the right with acceleration a_(A)=12tms^(-2) and a_(C )=3ms^(-2) . Here t is in second. The time when block B again comes to rest is
