Answer:
Ac=cd & ab=bd +common side so abc=dbc
same for ehf and ghf but difference in common right angle.

Step-by-step explanation:
Answer:
Equation of movement y(t)

Amplitude: 1 inch
Period: 0.628 seconds
Step-by-step explanation:
If there is no friction, the amplitude will be the length it was streched from the equilibrium. In this case, this value is 1 inch

The period depends on the mass and the spring constant.
The formula for the period is:

The model y(t) for the movement of the mass-spring system is
