An automated deep-sea research submersible has a total mass of 420 kg. During a descent maneuver, it undergoes an acceleration of 0.85 m/s2.
Calculate the magnitude of the resultant force acting on the submersible to produce this acceleration.
Use the equation:
force=mass×acceleration \text{force} = \text{mass} \times \text{acceleration} force=mass×acceleration57 exam-style questions on Edexcel GCSE Physics 2.3 Forces and Newton's laws, covering 2.3.1 Newton's first law, 2.3.2 Newton's second law, and 2.3.3 Weight and gravitational field strength.
