A compact, dense object with a mass of 3.20 kg is attached to a spring and is able to oscillate horizontally with negligible friction. The object is pulled to a distance of 0.200 m from its equilibrium position, held in place with a force of 19.0 N, and then released from rest. It then oscillates in simple harmonic motion. (The object oscillates along the x-axis, where x = 0 is the equilibrium position.) (a) What is the spring constant (in N/m)? N/m (b) What is the frequency of the oscillations (in Hz)? Hz (c) What is the maximum speed of the object (in m/s)? m/s (d) At what position(s) (in m) on the x-axis does the maximum speed occur? m (e) What is the maximum acceleration of the object? (Enter the magnitude in m/s2) m/s? () At what position(s) (in m) on the x-axis does the maximum acceleration occur? X= m (9) What is the total mechanical energy of the oscillating spring-object system (in))? (h) What is the speed of the object (in m/s) when its position is equal to one-third of the maximum displacement from equilibrium? m/s 0) What is the magnitude of the acceleration of the object (in m/s2) when its position is equal to one-third of the maximum displacement from equilibrium? m/s2
