What is the weight of the wretched Bananas in Newtons? I'm so confused

    What is the weight of the wretched Bananas in Newtons??? I'm so confused...


    Ok so I tried to list out all of the stuff I was given.

    Spring constant: k = 16.0 N/m
    Amplitude: A = 0.2 m
    Maximum speed: v = 0.434 m/s

    Maximum Kinetic Energy = Maximum Spring/Potential Energy
    (1/2)mv2 = (1/2)kA2
    (1/2)(0.4342)m = (1/2)(16)(0.22)
    0.094178m = 0.32
    m = 3.39 kg

    Oh wait I just realized they want it in Newtons...

    mg = (3.39)(9.8) = 33.29 = 33.3

    Nvm ^_^
