Question

in a C-L mechanical system, a spring of length 4.00 ft reaches 8.0 ft when a weight of 8.00 pounds is hung, it is released from a position that is 0.50 ft below the balance line with a speed of (2)^(1/2) upwards it is requested:

a. deduce the equation of movement

b. which are the amplitude and the period of movement

c. how many complete oscillations the counterweight will have done at 14 seconds

d. at which moment its counterweight reaches its extreme displacement on both sides of the equilibrium position

e. what is the position of the counterweight when t = 3.00 s
