Problem

A constant net force produces an acceleration of 3 m s−23\,\text{m\,s}^{-2} in an 8 kg8\,\text{kg} cart. The same force is applied to a 4 kg4\,\text{kg} cart on an identical surface. What is the acceleration of the 4 kg4\,\text{kg} cart? (a) 3 m s−23\,\text{m\,s}^{-2} (b) 6 m s−26\,\text{m\,s}^{-2} (c) 1.5 m s−21.5\,\text{m\,s}^{-2} (d) 12 m s−212\,\text{m\,s}^{-2}
