SUMMARY
The minimum mass difference required for an Atwood's machine with a friction resistance of 0.147 N to achieve non-zero acceleration is derived from the equations of motion. The relevant equations are a = g(m/M) - f/M and a = g(m/M). To find the mass difference (m), one must consider the total mass (M) of 250 g and the friction force (f). By substituting the values into the equations, the correct mass difference can be calculated to ensure the system accelerates when released from rest.
