A body of mass 4 gr attached to a vertical spring stretches it 160 cm to reach the equilibrium position. Approximate the acceleration of gravity by g=1000 cm/sec2, and neglect any air resistance.
a) Find a differential equation of the form y=F(y,y) for the displacement function y from the equilibrium position, with ypositive downwards. Use yp to denote de derivative y.
F(y,y)=
b) At t0=0 sec the body is pushed up an additional 2 cm and then released with an initial velocity of 5(31/2) cm/sec. Find the solution y of the equation in part (a), and also provide the amplitude A and the phase-shift in the interval (,].
y(t) =
A=
=
