Homework Statement
The spring constant of the spring is 23N/m and the mass of the object is 6kg. The spring is unstretched and the surface is frictionless. A constant force of 16N is applied horizontally to the object causing the spring to stretch.
Find the speed of the object after it has moved a distance of 0.32m.
Answer range: 0.470372 - 3.23253
Homework Equations
F=-mxw^2
v=w(A^2 - x^2)^(1/2)
The Attempt at a Solution
F=-w^2mx
where k=mw^2
16=kx , x=16/23 m ---Amplitude A
v=w ( (16/23)^2 - (0.32)^2 )^(1/2)
v= 1.20935 m/s (wrong)
