To calculate the weight of an object on Mars, you can use the formula:
\[ \text{Weight} = \text{mass} \times \text{acceleration due to gravity} \]
Given:
- Mass = 16 kg
- Acceleration due to gravity on Mars = 3.8 m/s²
Now plug in the values:
\[ \text{Weight} = 16 , \text{kg} \times 3.8 , \text{m/s}^2 \]
\[ \text{Weight} = 60.8 , \text{N} \]
Rounding to the nearest whole number, the weight of the object on Mars is approximately 61 N.
Therefore, the correct answer is:
d. 61 N.
