QB3 (25 Marks) (a) Quantitatively describe the three (3) types of vibrations associated with the differential equation: 5f"(t) + f'(t) + 10f (t) = --2sin(t) (3) (3 Marks) (b). (. (0). Solve the differential equation: 5f"(t) + f'(t) + 10 (t) = 0,f(0) = 0; f'(0) = 4 (4) (ii). Determine the frequency and period of vibration; (iii) State the transient and steady state terms of the oscillation (iiv). Visualize the solution for t =(0:1:25) and comment on the observation. (9 Marks) (c). (i). (5) (ii). (iii). Solve the differential equation: f"(t) + f(t) = -2sin(t), f(0) = 0; f(0) = 1 Evaluate the frequency and period of vibration; Visualize the solution for t =(0:1:25) and comn (8 Marks) on observation.
