Question 6
A 14 kg weight is attached to a spring with constant k = 350 kg/m and subjected to an external force
F(t) = 294 cos(2t). The weight is initially displaced 4 meters above equilibrium and given an
downward velocity of 3 m/s. Find its displacement for t> 0, with y(t) measured positive upwards.
