Question 19

On Mars, the gravitational field strength is 3.7 N/kg. Calculate the gravity force (weight) for a 120 kg Mars rover.

Use the equation:

gravity force=mass×gravitational field strength \text{gravity force} = \text{mass} \times \text{gravitational field strength} gravity force=mass×gravitational field strength
