A 200 g ball attached to a spring with spring constant

2.50 N/m oscillates horizontally on a frictionless table. Its velocity is 18.0 cm/s when x = -5.00 cm.

A. What is the amplitude of oscillation?

B. What is the speed of the ball when x = 3.00 cm?

2. Relevant equations

A. [tex]\omega[/tex] = sqrt k/m = sqrt 2.50/.200

v(t) = A*[tex]\omega[/tex]*sin([tex]\omega[/tex]t)

t = 0

v(t) = A[tex]\omega[/tex]

B. V_{x}^{2}= [tex]\omega[/tex]^{2}(A^{2}- x^{2})

3. The attempt at a solution

I've tried several times to get a solution and I have never gotten the same answer twice...

A. [tex]\omega[/tex] = 3.54

A = 5.09 cm

B. When x = 3.00 cm, V = 14. 56 cm.

Neither of these answers are correct and I'm not sure what I am doing wrong. I am doing everything as explained to me in class. I'm so confused...
