Problem

An ideal spring with spring-constant

k

is hung from the ceiling and a block of mass

M

is attached to its lower end. The mass is released with the spring initially unstretched. Then the maximum extension in the spring is (1)

\frac{4Mg}{k}

(2)

\frac{2Mg}{k}

(3)

\frac{Mg}{k}

(4)

\frac{Mg}{2k}
