A 5.00 partridge is suspended from a pear tree by an ideal spring of negligible mass. When the partridge is pulled down 0.100 below its equilibrium position and released, it vibrates with a period of 4.20
What is its speed as it passes through the equilibrium position?
What is the magnitude of the acceleration when it is 5.00×10?2 above the equilibrium position?
What is the direction of the acceleration when it is 5.00×10?2 above the equilibrium position?
