Solve question via relative motion analysis of two particles using translating axes

The left figure shows a block m1 with two inclined sides. Its left inclined side remains in contact with a fixed inclined plane and its right inclined side remains in contact with the surface of a second block m2 that can slide horizontally. At a certain instant, the speed of block 2 is v2=2m/s to the right, and its acceleration a2=0.5m/s2 to the left. Part A Determine the magnitude of the absolute velocity of block m1 at that instant, and its angle v with respect to the horizontal. Part B Determine the magnitude of the absolute acceleration of block m1 at that instant, and its angle a with respect to the horizontal. The left figure shows a block m1 with two inclined sides.
