Consider a loop in the standing wave created by two waves (amplitude 5.58 mm and frequency 115 Hz) traveling in opposite directions along a string with length 3.98 m and mass 145 g and under tension 42.4 N. At what rate does energy enter the loop from (a) each side and (b) both sides? (c) What is the maximum kinetic energy of the string in the loop during its oscillation?
