Question

Image for 4. A heavy stone of mass 45 kg is hung from the ceiling by a thin wire that is 1.73 m long. You gently pluck

Answer 1

Answer #1

First, the velocity of the pulse is found from

d = vt

v = d/t = 2(1.73)/(6.98 X 10^-3)

v = 495.7 m/s

Then v = sqrt(T/u)

495.7 = sqrt[(45)(9.8)/u]

u = 1.79 X 10^-3 kg/m

A heavy stone of mass m is hung from the ceiling by a thin 8.25-g wire that is 100 cm long. When you gently pluck the upper end of the wire, a pulse travels down the wire and returns 3.6 ms later, having reflected off the lower end. The speed of sound in the room is 344 m/s, and the stone is heavy enough to prevent the lower end of the wire from moving. If the wire is vibrating in...

A uniform thin rod of mass m and length 5b is suspended from the ceiling by a single string of length 2b attached to one end (this end of the rod is called P1). Thus in equilibrium the string and rod hang straight down and the lower end of the rod is a distance 7b from the ceiling (this end of the rod is called P2). The motion is constrained to be in a fixed vertical plane, so we have...

An ideal spring dangles from the ceiling at its relaxed length of 5 cm. A 3-kg mass is carefully hung from the end of the spring while the spring is relaxed, and then the mass is released from rest at time t = 0, which begins to stretch the spring. The spring stretches to its maximum length at time t = 130 ms when the mass reaches its lowest point. Then the mass returns upward, shortening the spring. The oscillation...
