    (See attached file for full problem description with symbols and diagrams)

    1.) A block hangs in equilibrium from a vertical spring. When a second identical block is added, the original block sags by 6.00 .
    Part A
    What is the oscillation frequency of the two-block system?

    2.) The figure is the velocity-versus-time graph of a particle in simple harmonic motion.

    Part A

    What is the position at

    3.) A 90.0 mass on a 1.50 -m-long string is pulled 7.80 to one side and released.
    Part A
    How long does it take for the pendulum to reach 3.40 on the opposite side?

    1.) A block hangs in equilibrium from a vertical spring. When a second identical block is added, the original block sags by 6.00 .
    Part A
    What is the oscillation frequency of the two-block system?
    **In Hz

    The spring constant is give by
    K = (F2 - F1)/(L2 - L1) = mg/0.06
    Hence the frequency of the system is

    ...
