Part A Different mass crates are placed on top of springs of uncompressed length Lo and stiffness k. (Figure_1) The crates are released and the springs compress to a length L before bringing the crates back up to their original positions. Rank the time required for the crates to return to their initial positions from largest to smallest Rank from largest to smallest. To rank items as equivalent, overlap them. View Available Hint(s) Reset Help k = 20 N /m 10 N/m k=5N/m k = 5N/m L = 5 ci L- 5 cm _ = 10 cm L =5 cm Lo = 15 cm Lo = 10 cm - 20 cm Lo = 10 cmLI k = 15 N/m = 10 N/m L - 10 cm L - 5 cm Lo = 15 cm Lo = 20 cin Figure 1 of 1 largest smallest ) The correct ranking cannot be determined
