Description
A weight suspended from a spring executes damped vibrations vith a period of 3 sec . If the damping
factor decreases by 82% in 7 sec , find the acceleration of the weight when it is 3 inches below its
equilibrium position and is moving upward with a speed of 2ftsec. (The positive direction
is downward.)
When the weight is 3 inches below its equilibrium position and moving upward with a speed of 2ftsec,
its acceleration is ftsec2.
(Do not round until the final answer. Then round to the nearest hundredth as needed.)
