A Spring with a 16-Kg Mass Has Natural Length $0.8 \mathrm {~m}$

question 91

Short Answer

A spring with a 16-kg mass has natural length $0.8 \mathrm {~m}$ and is maintained stretched to a length of $1.2$ $\mathrm { m }$ by a force of $19.6 \mathrm {~N}$ . If the spring is compressed to a length of $0.4 \mathrm {~m}$ and then released with zero velocity, find the position $x ( t )$ of the mass at any time $t$ .
