1. A .6kg block is hung from a spring with a force constant of 25 N/m. Calculate the displacement of the spring from its equilibrium length, assuming it is hung vertically and neglecting the spring mass.
2. The mass in (1.) is pulled downward by an additional 6 cm and held steady. Calculate the potential energy input corresponding to this additional displacement.
3. Calculate the period of oscillation of the mass/spring system once the object is released.
4. Write an expression for the vertical motion of the system, along the y (vertical) axis, in the form: ?(?) = ? cos(?t) (Use the appropriate values of A and ω in your expression).
5. Calculate the maximum speed of the oscillating object and its maximum kinetic energy. Do your results make sense based off what you got in 2?
(I posted all 5 parts but could you answer only 4 and 5? Thank you!)
