Martin caught a fish and wanted to know how much it weighed, but he didn't have a scale. He did, however have a stopwatch, spring, and a 4.90N weight. He attached the weight to the spring and found that the spring would oscillate 20 times in 65 seconds. Next he hung the fish on the spring and found that it took 220 seconds for the spring to oscillate 20 times. What is the weight of the fish? Can someone please help me solve this problem? Thanks for any help.
