Expert Solution
given data:
mass spring system subjected to half sine pulse having
time duration T=0.25
sec
mass of spring = 20gm
spring stiffness = 197.4 dynes/cm=197.4 gm/sec2
need to find out 
?
1 dyne =gm.cm/sec2=

=.785 which is less than 1.
as we know when the resonance frequency is less than natural frequency system is in oscillation conditaion

A mass on a spring is subjected to an external force that looks
like a triangular wave:
F(t) = 1+t from t=-1 to 0
F(t) = 1-t from t=0 to t=1 Periodicity = 2
The differential equation for the position of the mass (using
Newton’s law) ends up being: x’’(t) + 2x’(t) + 101x(t) = F(t)

A mass m, stretches horizontally from a spring which has spring
constant k, and is subjected to a retarding force equal to bv,
where v is the instantaneous velocity of the mass. A particle of
mass 10 gm moves along the x axis under the influence of two
forces. The first is a force (in g cm s-2) of attraction to the
origin O which is 40 times the distance from O. The second is a
damping force proportional to...
