A partridge of mass 5.05 kg is suspended from a pear tree by an ideal spring of negligible mass. When the partridge is pulled down 0.100 m below its equilibrium position and released, it vibrates with a period of 4.15 s.
i figured out the first three parts, but part four has me stuck.
What is its speed as it passes through the equilibrium position?
.151m/s
What is its acceleration when it is 0.050 m above the equilibrium position?
-0.115 m/s^2
When it is moving upward, how much time is required for it to move from a point 0.050 m below its equilibrium position to a point 0.050 m above it?
0.692s
The motion of the partridge is stopped, and then it is removed from the spring. How much does the spring shorten?
I have no idea...
ive been stumped on this for a while now. i honestly have no idea how to even approach this part. can anybody help me out??
