A 99-kg box hangs from the ceiling of a room suspended from a spring with a force constant of 525 N/m. the unstressed length of the spring is 0.450 m.

a) Find the equilibrium position of the box.

b) An identical spring is stretched and attached to the ceiling and the box, and its parallel with the first spring. Find the frequency of the oscillations when the box is released.

c) What is the new equilibrium position of the box once it comes to rest?

An ideal spring hangs from the ceiling. A 2.15 kg mass is hung from the spring, stretching the spring a distance d = 0.0905 m from its original length when it reaches equilibrium. The mass is then lifted up a distance L = 0.0225 m from the equilibrium position and released. What is the kinetic energy of the mass at the instant it passes back through the equilibrium position?

A 1.50-kg object is attached to a spring and placed on frictionless, horizontal surface. A horizontal force of 28.0 N is required to hold the object at rest when it is pulled 0.200 m from its equilibrium position (the origin of the x axis). The object is now released from rest from this stretched position, and it subsequently undergoes simple harmonic oscillations. a.)Find the force constant of the spring. b.)Find the frequency of the oscillations. c.)Find the maximum speed of...
