On Earth, the gravitational force of a certain military drone is 6.0 kg. What is the helicopter's gravitational force if it is sitting on Mars?

On Earth, g = 9.8 ms2

On Mars, g = 3.71 ms2

To find the gravitational force acting on the drone when it is on Mars, you can use the formula:

\[ F = m \cdot g \]

where:

  • \( F \) is the gravitational force,
  • \( m \) is the mass of the object,
  • \( g \) is the acceleration due to gravity.

First, you need to find the mass of the drone. The gravitational force on Earth can be calculated as follows:

\[ F_{Earth} = m \cdot g_{Earth} \] \[ F_{Earth} = 6.0 , \text{kg} \cdot 9.8 , \text{m/s}^2 \] \[ F_{Earth} = 58.8 , \text{N} \]

Now that you know the force and the gravitational acceleration on Earth, you can rearrange the formula to find the mass:

\[ m = \frac{F_{Earth}}{g_{Earth}} = \frac{58.8 , \text{N}}{9.8 , \text{m/s}^2} = 6.0 , \text{kg} \]

Now, calculate the gravitational force on Mars using the formula again:

\[ F_{Mars} = m \cdot g_{Mars} \] \[ F_{Mars} = 6.0 , \text{kg} \cdot 3.71 , \text{m/s}^2 \] \[ F_{Mars} = 22.26 , \text{N} \]

Therefore, the gravitational force acting on the drone while sitting on Mars is 22.26 N.
