Problem

A 2 kg2\,\text{kg} cart on a friction-free track is pushed horizontally with a constant force of 8 N8\,\text{N}. The cart exerts an equal and opposite force on the person’s hand. What is the acceleration of the cart? (a) 0 m s−20\,\text{m}\,\text{s}^{-2} (b) 4 m s−24\,\text{m}\,\text{s}^{-2} (c) 2 m s−22\,\text{m}\,\text{s}^{-2} (d) 8 m s−28\,\text{m}\,\text{s}^{-2}
