Problem: A 78.5kg man is about tocompletea bungee jump. If the bungee cord has a spring constant of 150 N/m, determine the period of oscillation that we will experience. m= 78.5 Kg k= 150 N/m T=? Relevant equations: T= 2(pi)√(m/k) The attempt at a solution T= 2(pi)√(78.5kg/150 N/m) I get, T=4.54s ............................................................................................................................... 2nd Problem: A 5.00 kg mass oscillates on a spring with a frequency of 0.667 Hz. Calculate the spring constant. m= 5.00 Kg f= 0.667 Hz k= ? Relevant equations: T= 2(pi)√(m/k) T=(1/f) The attempt at a solution T= (1/0.667Hz) T= 1.499s T= 2(pi)√(m/k) I rearange and get: k=87.84 N/m If anyone can confirm or let me know if I did something wrong it would be great! Thanks in advance!
