When a mass hanging from a spring is pulled down and then released, the motion is called __________ . if there is no frictional force to retard the motion, and the motion is called ______ if there is friction.
Given two sides and the included angle, the first thing to do to solve the triangle is to use the Law of Sines .
Find the area of the triangle. Round answer to two decimal places.
The displacement d (in meters) of an object at time t (in seconds) is given
(a) Describe the motion of the object.
(b) What is the maximum displacement from its resting position?
(c) What is the time required for one oscillation?
(d) What is the frequency?
If the distance d of an object from its rest
position at time t is given by a sinusoidal graph, the motion of the object is simple harmonic motion.
