Dynamics Physics help

    Dynamics Physics help urgent

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

    Sara wonders what the normal force on her 1.0 kg water bottle would be if she tries to lift it with 4.0 N (she used a Newton spring scale to measure her applied force). What is the bottle's acceleration?

    2. Relevant equations

    Fg = mg

    3. The attempt at a solution

    I found Fg which is 9.8 N downwards.
    Not sure what to do after this.
    Any help, please?
