Correct A spring of negligible mass has force constant k- 1400 N/m. Corect answer is shown. Your answer 7.0-10-7x10m was elther rounded differently or used a different number of signiticant figures than required for this part IDENTIFY: The elastic potental energy of the spring is proportional to the square of compression length. SET UP: U ke EXECUTE: U-ka 2(3.40 J) 1400 N/m so 6.97 x 10 m Part B You place the spring verticaly with one end on the fioor. You then drop a m1.30 kg book onto it hom a height of h0 800 m above the lop of the spring.
