2. ### A mass-spring system oscillates with an amplitude of 5.80 cm. If the spring constant is 275 N/m and the mass is 582 g,?

1) E = 1/2 k A^2 E = 0.5 * 275 * 0.058^2 = 0.46 J 2) v = w A = sqrt(k/m) A v = sqrt(275/0.582) * 0.058 = 1.26 m/s 3) a = w^2 A = (k/m) A a = (275/0.582) * 0.058 = 27.41 m/s^2
