Answer:
C)T
Explanation:
The period of a mass-spring system is:
As can be seen, the period of this simple harmonic motion, does not depend at all on the gravitational acceleration (g), neither the mass nor the spring constant depends on this value.

The answer is
"".
Explanation:
Taking into consideration a volume weight = 16 pounds originally extends a springs feet but is extracted to resting at 2 feet beneath balance position.
The mass value is =
The source of the hooks law is stable,
Number times the immediate speed, i.e .. Damping force
The m^2+m+12=0 and m is an auxiliary equation,
Therefore, additional feature
Use the form of uncertain coefficients to find a particular solution.
Assume that solution equation,
These values are replaced by equation ( 1):
Going to compare cos3 t and sin 3 t coefficients from both sides,
The cost3 t is 3A + 3B= 20 coefficients
The sin 3 t is 3B -3A = 0 coefficient
The two equations solved:
Replace the very first equation with the meaning,
equation is
The ultimate plan for both the equation is therefore
Initially, the volume of rest x(0)=2 and x'(0) is extracted by rest i.e.
Throughout the general solution, replace initial state x(0) = 2,
Replace x'(0)=0 with a general solution in the initial condition,
