    SHM(mass suspended vertically on spring)

    ok I just misunderstood the question. When I divided the 3.42 cm by 2 and reentered it to the formula I got the right answer. Thanks guys.

    SHM(mass suspended vertically on spring)

    Ok I thought about it for a while and thought I was on the right track but still got it wrong. This is what i did: F=k∆x mg=k∆x √(g/∆x)= √(k/m)=ω=2π(1/T) √(g/∆x)= 2π(1/T) T=2π√(∆x/g) and I got like .37 seconds. Was I on the right track?
