A massless spring hangs from the ceiling with a small object attached to its lower end. The object is initially held at rest in a position y_i such that the spring is at its rest length. The object is then released from y_i and oscillates up and down, with its lowest position being 14 cm below y_i.

(a) What is the frequency of the oscillation?
Hz

(b) What is the speed of the object when it is 12.0 cm below the initial position?
m/s

(c) An object of mass 275 g is attached to the first object, after which the system oscillates with half the original frequency. What is the mass of the first object?
g

(d) How far below y_i is the new equilibrium (rest) position with both objects attached to the spring?
m

an 10 kg object is hung from a spring attached to a fixed support. The spring constant of the spring is k=40 Nm**(-1) (I mean to the power of -1) Suppose an external downward force of magnitude f(T) = 20 e **(-2t) N is applied to the object, and damping due to air resistence occurs with damping constant beta = 40 N s m **(-1). Let y(t) denote the distance in meters of the object below its equilibrium position at...

From the end of a string (whose other end is firmly attached to the ceiling) we attach a mass m1.Similarly, we attach a mass m2 from the end of a different string. Both strings have equal lengths and the masses are barely in contact when they are hanging freely. We pull out both masses so that they form angles θ1and θ2, respectively, with their equilibrium (vertical) positions. We then release the masses such that there is an elastic, heads-on collision...
