Question 20

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×acceleration
