[ Switch to Standard Assignment View] Problem 14.44 A 4.10 block hangs from a spring with spring constant 1860 . The block is pulled down 4.20 from the equilibrium position and given an initial velocity of 1.80 back toward equilibrium. Part A What is the frequency of the motion? ANSWER: 3.39 Correct Part B What is the amplitude? ANSWER: 9.44 × 10 2 Correct Part C What is the total mechanical energy of the motion? ANSWER: 8.28 Correct Problem 14.70 An oscillator with a mass of 600 and a period of 0.400 has an amplitude that decreases by 1.10% during each complete oscillation.
