Homework Statement
a)When a mass is attached to the end of a vertical spring, the spring is stretched down 3 cm. If the mass is pulled down a bit farther and then released, what is the period of oscillation of the mass on the spring? b) if the mass moves through its equilibrium position at 50 cm/s, what is the amplitude of the oscillation?
Homework Equations
T= 2pi/v , w= srqt(g/L) , T=2pi/w
The Attempt at a Solution
I tried using w= srqt(g/L) because the problem only gives you with the radius of the ball, so i just that equation to find the angular velocity and than use w to find the period with T=2pi/w but i don;t get the right answer. which is 0.348 seconds.
for part b i just don;t even know how to start.
I need help?
