Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

A mass weighing 4 pounds is attached to a spring whose constant is 2 ib/ft. The medium offers a damping force that is numerically equal to the instantaneous velocity. The mass is
initially released from a point 1 foot above the equlibrium position with a downward velacity of 12 t/s. Determine the time (in s) at which the mass passes through the equilibrium
position. (Use g -32 /s for the acceleration due to gravity.)
Find the time (in s) after the mass passes through the equilibrium position at which the mass attains its extreme displacement from the equilibrium position.
What is the position (in t) of the mass at this instant?
