    Oscillating Spring in a Frictionless pulley system

    It would be equal to the hanging mass times acceleration, in this case, gravity. f=ma

    Oscillating Spring in a Frictionless pulley system

    netF=tension-weight right??

    Oscillating Spring in a Frictionless pulley system

    weight acts downwards, and tension acts upwards

    Oscillating Spring in a Frictionless pulley system

    I just realized I messed up my units on #3 by a power of 10. It should be .588 rather than .0588 and 470.4 rather than 47.4

    Oscillating Spring in a Frictionless pulley system

    I tried part two again based on you advice and I think I did it correctly. Fnet=ma T-mg=mg T=2mg T=2(.4)(9.8) T=7.84 N

    Oscillating Spring in a Frictionless pulley system

    here are the last two parts. Thank you for helping me!

    Oscillating Spring in a Frictionless pulley system

    I tried my best, but I am not sure how to work around finding tension with the spring involved

    Oscillating Spring in a Frictionless pulley system

    here is the free body diagrams, I am working on the rest

    Oscillating Spring in a Frictionless pulley system

    sorry, I am not very good at physics, the equilibrium extension is 0.2 meters

    Oscillating Spring in a Frictionless pulley system

    the spring at equilibrium is 0.2 meters

    Oscillating Spring in a Frictionless pulley system

    1. Draw Free body Diagram for each weight. 2. Solve for Tension in Rope. 3. Find Spring Constant. 4. Find omega (w, or angular velocity)
