A spring with natural length .5 m has length 50.5 cm with a mass of 2 gm suspended from it. The mass is initially displaced 1.5 cm below equilibrium and released with zero velocity. Find its displacement for t > 0.

Explanation:

#Using Hooke's Law show that,

#And, Newton's Law,

is the the force, is the spring constant and the compression length.

#Equating we find:

#Using differential equation:

   #Solve this differential equation

#The general solution for this equation is then given as:

#Using the boundary conditions,  at

Hence displacement at t>0 is given by

i would say the answer is food.

hope this !
