A 2.0 kg block is attached to a spring that obeys Hooke's Law. An amount of energy, 16 J, is done to stretch the spring. The block is then released and oscillates with a period of 0.30 s. What is the amplitude of the motion? 1 2 3 4 25% 25% 25% 25% 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 1. 38.0 cm 2. 19.0 cm 3. 9.5 cm 4. 4.3 cm
