Problem

A rocket engine provides a constant thrust of

4000\,\text{N}

. When it pushes an

800\,\text{kg}

space probe, the probe’s acceleration is

5\,\text{m\,s}^{-2}

. If the same engine is attached to a

2000\,\text{kg}

cargo module, the acceleration of the module will be a)

8\,\text{m\,s}^{-2}

2\,\text{m\,s}^{-2}

5\,\text{m\,s}^{-2}

12\,\text{m\,s}^{-2}
