A mass in hangs on a string that is connected to the ceiling. You pluck the string just above the mass, and a wave pulse travels up to the ceiling; reflects off the ceiling, and travels back to the mass. Compare the round-trip time for this wave pulse to that of a similar wave pulse on the same string if the attached mass is increased to 3.00 m. (Assume that the string does not stretch in either case and the contribution of the mass of the sting to the tension is negligible.)
