Please answer Part B

Review | Cons Correct A spring of negligible mass has force constant Correct answer is shown. Your answer 7.0-10-2 = 7x10-2m was either rounded differently or used a differ k = 1400 N/m. number of significant figures than required for this part. IDENTIFY: The elastic potential energy of the spring is proportional to the square of compression length. SET UP: Uel =- kx? EXECUTE: U =- kx2 so x = 20 2(3.40 J) ke 6.97 x 10 2 m 1400 N/m V Part B You place the spring vertically with one end on the floor. You then drop a m = 1.30 kg book onto it from a height of h = 0.800 m above the top of the spring. Find the maximum distance the spring will be compressed. Express your answer in meters to three significant figures. AEQ d = 0.12 m
