Asked by Mikhail
A partridge of mass 5.01kg 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 4.20s .
What is its speed as it passes through the equilibrium position?
What is its acceleration when it is 0.050 m above the equilibrium position?
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?
The motion of the partridge is stopped, and then it is removed from the spring. How much does the spring shorten?
