A deep-space research probe has a mass of 1400 kg. The probe's main engine accelerates it through the vacuum of space at 0.45 m/s2.
Calculate the resultant force producing this acceleration. State the unit.
Use the equation:
resultant force=mass×acceleration \text{resultant force} = \text{mass} \times \text{acceleration} resultant force=mass×acceleration57 exam-style questions on Edexcel GCSE Physics 2.3 Forces and Newton's laws. Each one has a worked solution and a mark scheme showing where the marks go.
