Question
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. The the maximum extension in the spring is
Options
A.
B.
C.
D.
Solution
Let x be the maximum extensions of the spring. From conservation of mechanical energy.
degrease in gravitational potential energy = increase in elastic potential energy
∴ Mgx =
kx2 or x =
