What is the output of a system with the transfer function s/(s + 3)^2 and subject to a unit step input at time t = 0?

0

Explanation:

output =transfer function H(s) ×input U(s)

here H(s)=

U(s)= for unit step function

output =H(s)×U(s)

=×

=

taking inverse laplace of output

output=t×

at t=0 putting the value of t=0 in output

output =0
