Problem

A block is attached to a horizontal spring of constant

120\,\text{N/m}

on a frictionless table. The block is pulled so the spring stretches

0.25\,\text{m}

and is then held stationary. What is the magnitude of the force required to hold the block at this position? (a)

7.5\,\text{N}

(b)

120\,\text{N}

(c)

30\,\text{N}

(d)

15\,\text{N}
