Figure attached below. You have a big block of mass M and a small block of mass m. When m=3kg, the acceleration of the large block is 0.6ms-2. When m=4kg, the acceleration of the large block is 1.6ms-2. The dynamic friction coefficient between the large block and the surface it slides on is μ. There is no friction between any other surface. Questions: a) Express the relationship between the movement of block m and block M b) Derive expressions for the motion of block m and block M. c) Determine the mass of block M and the dynamic friction coefficient, μ, between it and the surface it slides on.
