Problem

2\,\text{kg}

block resting on a smooth horizontal table is attached to a fixed pivot point by a spring of natural length

0.3\,\text{m}

and stiffness constant

k = 200\,\text{N/m}

. The block is made to rotate with an angular velocity of

5\,\text{rad/s}

. Calculate the extended length of the spring during this motion.
