Concept

# Problem: Two blocks of unequal mass are tied together with a massless string that does not stretch and connected via a frictionless and massless pulley. Mass one, M1 rests on a frictionless table top. Mass two, M2, is released and both blocks begin to move. The blocks accelerate at the same rate since they are connected. What is the acceleration?A. Cannot be DeterminedB. ZeroC. gD. g/2E. A value greater than g.F. A value between zero and g.
