1-suppose-the-equation-of-motion-for-free-undamped-motion-of-a-mass-spring-system-is-x-t-4cos-pa166

1) suppose the equation of motion for free undamped motion of a mass spring system is x(t)=4cos t - 3 sin t . Find the amplitude of the oscillations.

2) suppose the equation of motion for free undamped motion of a mass spring system is x(t)= 5 cos t - 12 sin t. The equation of motions can also be written as.

SOLUTION:

The equation of motion for the free undamped motion of a mass-spring system is given by:
