Figure shows a small block
A of mass
m kept at the left end of a plank
B of mass
M=2m and length
λ. The system can slide on a horizontal road. The system is started towards right with the initial velocity
v. The friction coefficients between the road and the plank is
1/2 and that between the plank and the block is
1/4(b) displacement of block and plank with respect to ground till that moment?
