Newton 2nd Law word problem help

    "Newton 2nd Law" word problem help

    1. The problem statement, all variables and given/known data

    When the click beetle jumps in the air, its acceleration upward can be as
    large as 400.0 times the acceleration due to gravity. (An acceleration
    this large would instantly kill any human being.) For a beetle whose
    mass is 40.00 mg, calculate the magnitude of the force exerted by the
    beetle on the ground at the beginning of the jump with gravity taken
    into account. Calculate the magnitude of the force with gravity ne-
    glected. Use 9.807 m/s2 as the value for free-fall acceleration.

    m= 4.00 × 10−5 kg
    g = 9.807 m/s2
    anet = (400.0)g

    2. Relevant equations
    i think

    3. The attempt at a solution

    I am really lost on what to do, maybe if somebody could give me the initial setup and explain why i will be able to complete the problem

    Forget about it, I don't have any more time to work on my homework, and this hasn't been looked at a single time so, don't even bother working on it.
