hard physics question!! help plz
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)
w^2= k/m
x = Asin(wt)
F=kx
dunno wat else??
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.
