An open water tanker moving on a horizontal straight road has a cubical block of cork floating over its surface if the tanker has an acceleration of `a` as shown, the acceleration of the cork w.r.t container is ignore viscosity.

A circular disc with a groove along its diameter is placed horizontally on a rough surface. A block of mass 1 kg is placed as shown. The co-efficient of friction between the block and all surfaces of groove and horizontal surface in contact is mu=2/5 . The disc has an acceleration of 25m//s^2 towards left. Find the acceleration of the block with respect to disc. Given cos theta=4/5 , sin theta=3/5 .
