EXAMPLE 13.6 The Vibrating Object-Spring System GOAL Identify the physical parameters of a harmonic oscillator from its mathematical description PROBLEM (a) Find the amplitude, frequency, and period of motion for an object vibrating at the end of a horizontal spring if the equation for its position as a function of time is * - (0.250 m) cos( 1) (b) Find the maximum magnitude of the velocity and acceleration. (c) What are the position, velocity, and acceleration of the object after...
REMARKS In evaluating the sine or cosine function, the angle is in radians, so you should either set your calculator to evaluate trigonometric functions based on radian measure or convert from radians to degrees. QUESTION If the mass is doubled, is the magnitude of the acceleration of the system at any position doubled, halved, or unchanged? doubled, halved, or unchanged? PRACTICE IT Use the worked example above to help you solve this problem.(a) Find the amplitude, frequency, and period of...
