1. The problem statement, all variables and given/known data A particle in SHM is subject to a driving force F(t)= ma*e^(-jt). Initial position and speed equal 0. Find x(t). 2. Relevant equations F = -kxdx = mvdv F(t) = F(0)*e^(iωt) x(t) = Acos (ωt +φ) 3. The attempt at a solution I have no idea how to deal with the exponential term. I know I can put the t in e^(-jt) in terms of v, but that makes integration awfully messy. Any tips? Thanks!
