Homework Help: Does this physics homework problem make sense?

  1. Dec 9, 2008 #1
    1. The problem statement, all variables and given/known data
    A 0.85kg mass oscillating on a spring w/ spring constant of 45 N/m. How do i determine angular frequency?
    A 0.85kg mass oscillating on a spring w/ spring constant of 45 N/m. This object reaches a maximum position of 12 cm from equilibrium. Determine:
    a.) angular frequency of this mass
    b.) force
    c.) acceleration
    d.) elastic potentional energy
    e.) kinetic energy
    f.) velocity that it experiences at its maximum position.
    g.) force
    h.) acceleration
    i.) potential elastic energy
    j.) kinetic energy
    k.) velocity that it experiences at the equilibrium position.

    2. Relevant equations

    3. The attempt at a solution
    okay so i got parts a through e, but for g through j... didnt i already answer those in b through e?

    Hi livblue23,

    I could be wrong (having the word Determine appear right before f is a bit confusing), but do they mean to evaluate b-f at the maximum position, and g-k at the equilibrium position?

    There are two statements in the problem. a to e is related to the first statement. The rest for second statement. Try.
