The damped motion of a vibrating particle is defined by the position vector r = x1 [1??1/(t+1)]I
Question:
The damped motion of a vibrating particle is defined by the position vector r = x1 [1??1/(t+1)]I + (y1e??πt/2 cos2πt)j, where t is expressed in seconds. For x1 = 30 in. and y1 = 20 in., determine the position, the velocity, and the acceleration of the particle when
(a) t = 0,
(b) t = 1.5 s.
