A vertical spring with constant 41.16 N / m rests in its equilibrium position hanging from the ceiling. On
its lower end, a mass of 1.68 kg is hung and it is stretched. When the particle has traveled a distance:0.4
m downward (measured from the equilibrium position), calculate the work done by the spring Wsaring
and by the force of gravity WgraVÜty respectively:
a) Wing= 3.2928 J and Weravity = -6.5856 J
b) Wine=-3.2928 J and Weravity= 6.5856 J
c) Wsrine= -3.2928 J and Weravity = -6.5856 J
d) Wing= 3.2928 J and Weravity = 6.5856 J
