Let Feat (t) = 0, m =1, k =121, b= 22. 1. The equation my" + by' + ky = Feat (t) will have the "critically damped" solution a. y (t) = 4ellt b. y (t) = e-lit + te-lit c. y (t) = cos(11t) + sin(11t) d. y (t) = ellt cos(11t) + ellt sin(11t) (enter a, b, c, or d) 2. Will the solution have oscillations? a. no b. yes (enter a or b) 3. What is the limit of the solution as t -> co ? a. 4 b. -4 c. O d. oo (enter a, b, c, or d)
