Answer Happy

is a force oscillation problems, please put step by step, and if you use trig adentities put which one you are using.
1. Find the solution y(t). (50%) The exciting force r(t)(g.m/sec) is illustrated as below. The coefficients in the mass-spring system are m=lg , k=4g/sec2. The initial conditions are y(0) =y'(0) = = ' 0. tr(t) IN 24 |3 4 - IN
