Amass m 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 speed of this wave pulse, v 1, to that of a similar wave pulse on the same string if the attached mass is increased to6.13m, v2. (assume that the string does not stretch in either case and the contribution of the mass of the string to the tension is negligible.) "1.163 the speed of the pulse in the second case is faster than in the first case 、
