## Homework Statement

A massless spring of spring constant

**k = 74 N/m**is hanging from the ceiling. a 490 g mass is hooked onto the unstretched spring and allowed to drop.

A) Find the amplitude

B) Find the period of the resulting motion

## Homework Equations

f = 1/T

F=-kx

x(t) = Acos (omega) t

omega = sqrt( k / m )

x(t) = Acos(omega * t + phi )

omega = sqrt ( g / L )

T = 2*PI * sqrt ( L / g )

## The Attempt at a Solution

I'm lost in this chapter and have no idea where to start, i was curious if someone could help step me through this problem, would help me a ton.

Thanks!
