A block A of mass m connected with a spring of force constant k is executing SHM. The displacement time equation of the block is x=`x_(0) + a sinomegat`. An identical block B moving towards negative x -axis with velocity `v_(0)` collides elastically with block A at time t=0. Then

displacement time equation of A after collision will be `x=x_(0) - v_(0)sqrt(m/k)sinomegat`

displacement time equation of A after collision will be `x=x_(0)+v_(0)sqrt(m/k)sinomegat`

Velocity of b just after collision will be a `omega` towards positive x-direction.

velocity of B just after collision will be `v_(0)` towards positive x-direction.
