Answer:
The equation that represents the motion of the string is given by:
 .....[1] where t represents the time in second.
     .....[1] where t represents the time in second.
Given that: A = 0.6 cm (distance above its resting position) , k = 1.8(damping constant) and frequency(f) = 105 cycles per second.
Substitute the given values in [1] we get;
 
  
or
 
  
(a)
The trigonometric function that models the motion of the string is given by:
 
(b)
Determine the amount of time t that it takes the string to be damped so that 
Using graphing calculator for the equation 
  
 
let x = t (time in sec)  
Graph as shown below in the attachment: 
we get:
the amount of time t that it takes the string to be damped so that  is, 0.5 sec
 is, 0.5 sec
