## Homework Statement

A block with mass

*m*= 1.7 kg attached to the end of a spring undergoes simple harmonic motion on a horizontal frictionless surface. The oscillation period is

*T*= 4.3 s and the oscillation amplitude is

*A*= 29.6 cm. When the spring is unstretched the block sits at a distance

*L*= 1.7 m from a wall. Suppose we snap the spring at the very moment the block passes through the equilibrium point towards the wall. Calculate the time it takes for the block to hit the wall.

## Homework Equations

w=2*Pi*f=2*Pi/T=sqrt(k/m)

x=Acos(wt)

## The Attempt at a Solution

w=2*Pi/4.3=1.46. I'm not sure how to go about using the above formulas
