3. A spring-mass system consists of a mass weighing 10 kg and a spring with stiffness of 1000 N/m. The mass is subjected to resonance by a harmonic force F(t) = 15 cos wt N. The initial condition is given as the initial position=0 and the initial velocity=0. Find the amplitude of the forced motion at the end of (a) 1.5 cycle and (b) 2.25 cycles.
