Avibration absorber, which is a spring-mass system (k2, m2), is added to a system (k, mi) subject to a harmonic force f(t) = fo cos @t. (a) derive the amplitudes of steady-state response for mi and m2. (b) find the relation between k2 and m2 that leads to no steady state vibration of mi.

1. a net force of 100 newton’s is applied to a wagon for 5 seconds. this causes the wagon to undergo a change in momentum of
