Chapter 14, Problem 10Q
A 100-g mass hangs from a long cord forming a pendulum. The mass is pulled a short distance to one side and released from rest. The time to swing over and back is carefully measured to be 2.0 s. If the 100-g mass is replaced by a 200-g mass, which is then pulled over the same distance and released from rest, the time will be (a) 1.0 s, (b) 1.41 s, (c) 2.0 s, (d) 2.82 s, (e) 4.0 s.

A simple pendulum, consisting of a mass of 2.0 kg, is attached to the end of string with unknown length. The mass is held out horizontally, and then released from rest. What must be the length of the string (m) if the speed of the mass at the bottom of the swing is 8.4 m/s
A mass m = 6.6 kg hangs on the end of a massless rope L = 2.04 m long. The pendulum is held horizontal and released from rest.
Now a peg is placed 4/5 of the way down the pendulum’s path so that when the mass falls to its vertical position it hits and wraps around the peg. As it wraps around the peg and attains its maximum height it ends a distance of 3/5 L below its starting point (or 2/5 L from its lowest point).
1. How fast is the mass moving at the top of its new path (directly above the peg)?
m/s
2) Using the original mass of m = 6.6 kg, what is the magnitude of the tension in the string at the top of the new path (directly above the peg)?
N
This time the pendulum is 1.04 m long. Suppose you start with the pendulum hanging vertically, at rest. You then give it a push so that it starts swinging with a speed of 1.29 m/s. What maximum angle (in degrees) will it reach, with respect to the vertical, before falling back down?
