Unformatted text preview: 21) a) Newton's second law says that F = ma. The acceleration of each block is proportional to the force applied to each block. We will call M the mass of the first block, A that block's acceleration, m the mass of the second block, and a the second block's acceleration. If we know that we apply the same horizontal force to both blocks, then we know that F = MA and F = ma, so MA = ma. If we measure the accelerations A and a, then we can find a relation for the mass of one block relative to the other: M/m = a/A. If we know one of the masses, then we can solve for the other. b) 22) 23) ...
