The system is released from rest with no slack in the cable and with the spring compressed by $0\mathrm{.}1$

m and the constant force $P=120N$ acting on the cylinder. Calculate the speed of the cylinder at

the instant when the spring is undeflected and the maximum stretch of the spring. Use $m=6kg,$

$k=600\frac{N}{m},$ and $=30.$ The pulley and the wheels of the cart are frictionless. $(v=1\mathrm{.}29\frac{m}{s},$

$=0\mathrm{.}5m)$
