Chapter 12 Worksheet
When a 50gram mass is attached to a certain spring, is oscillates with an amplitude of 5 cm and frequency
of 4.0 Hz.
A watch is started at
t
= 0 at the instant the mass is at a point of maximum amplitude to the
right of the equilibrium point.
Later, this mass is removed from the spring and replaced with a 133gram
mass.
1)
What is the spring constant of the spring?
2)
What is the maximum speed of the 50gram mass?
3)
What is the total energy of the system?
4)
What is the speed of the mass when it is 2 cm from the equilibrium position?
5)
What is the acceleration of the mass when it is 2 cm from the equilibrium position?

6)
What is the location of the mass at
t
= 1.27 s?
7)
What is the speed of the mass at
t
= 1.27 s?
8)
What is the acceleration of the mass at
t
= 1.27 s?
9)
What is the period of the oscillation of the 133gram mass?
A simple pendulum is made up of a 400g mass attached to a 1.30m string.
It is pulled to right a distance
of 10 cm and then released from rest at time
t
= 0.
This is the end of the preview.
