H, can you help me solve this two problems with detailed explanation please?

______ __ ___- ..___ I: ___ ______ A l/4-kg mass is attached to a spring with stiffness 3 Him. The damping constant fer the system is 2 Nsechn. If the mass is pushed 50 cm to the left of equilibrium and given a leftward velocity of 2 mt'sec, when will the mass attain its maximum displacement to the left? 2. Determine the first three nonzero terms in the Taylor polynomial series approximations for the following IVP. "+y+ y' = cos10t, y(0)=0, y'(0)=1
