A vertical spring (ignore its mass), whose spring stiffness constant is 900 N/m, is attached to a table and is compressed down 0.110 m.
(a) What upward speed can it give to a 0.300 kg ball when released?
-----------m/s
(b) How high above its original position (spring compressed) will the ball fly?
------m
Now if I am following my lecture notes correctly for part a)
I am using the equation is that V^2=KX^2
-------
mass of ball
so when we out it all out it should be v^2=900n/m(-.110m)^2
-----------------
.300 kg
-------------------------->v=6.02 m/s but that answer is wron apparently. I don't know where I am going wrong.
