Q2. Solve the following two problems step by step:markss the displacement of a body in a damped mechanical system. Considering zero externalforces, satisfies the following differential equation:2d2sdt2+6dsdt+4.5s=0where t represents time. If initially, when t=0,s=0 and dsdt=4, Find the displacement sin termsoft.b.2Mofabeam is given by:dMdx-wx+wl=0Such that w and l are constants. Determine Min terms ofx given: M=12wl2 when x=0
