Question 1. The equation of motion for a damped linear pendulum is
(d^2 θ)/?dt?^2 +2γ dθ/dt+ω^2 θ=0,
where ω=√(l⁄g) and γ are positive constants, with l the length of the pendulum and g gravity. If l=1, g=9.81 and γ=1/4 and θ(0)=3, how long does it take the pendulum swinging from rest to reach the position θ=0. How long does it take to reach θ=0 a second time?
