**hard physics question!! help plz**

## Homework Statement

How do I solve the 2 questions below?:

Questions 23 24

A 0.l kilogram block is attached to an initially unstretched spring of force constant k = 40 newtons per meter as shown above. The block is released from rest at time t = 0. (the image is attached below).

23. What is the amplitude of the resulting simple harmonic motion of the block?

(A) m (B) (C) (D) (E) 1m

24. At what time after release will the block first return to its initial position?

(A) (B) (C) (D) (E)

## Homework Equations

w^2= k/m

x = Asin(wt)

F=kx

dunno wat else??

## The Attempt at a Solution

I tried plugging in those 3 equations together and manipulating equations. couldn't get anything though. Someone please help. I think I'm missing an important equation.
