    Hi Tomate Supra!

    Thanks for your question!

    First, let's check what we know and what we can deduce from the statement:

    • The Perseverance robot has a mass of 1025 kg. Its mass on Earth is the same as that on Mars.

    Let's check what we are looking for:

    • The weight of Perseverance on Mars

    So, to find the answer to the question, we must use the weight formula:

    $$ P = m \cdot g $$

    Legend:

    • P: weight (N)

    • m: mass ( kg)

    • g: gravitational acceleration constant of the star ( \(m / s ^ 2 \))

    We know the value of m. The value of g should probably be given in the question. In this case, the value of the gravitational acceleration constant on Mars is \( 3.72 m / s^2 \).


    Thus, we replace the known values ​​in the formula:

    $$ P = m \cdot g $$

    $$ P = 1025kg \cdot 3.72 m/s^2 $$

    $$ P = 3813N $$

    By doing this, we find the final answer.

    Let us know if we can help you with anything else!
