Question
A musical note on a piano has a frequency of 40 Hz. If the tension in the 2-m
string is 308 N, and one-half wavelength occupies the string, what is the mass of
the wire?
O 0.031 kg
0.019 kg
0.024 kg
0.040 kg
0.047 kg
A simple pendulum is made of a 2 m-string and a bob of mass m. At t = 0, the
pendulum is at its equilibrium position and is given an initial velocity v = 0.2 m/s.
The maximum angular speed. e'max., is:
08 rad/s
