Feedback & Control Systems - Time Response

PLEASE ANSWER BASED ON THE 2ND PICTURE. ILL LIKE IT AFTER

For the transfer function
shown below, find the
locations of the pole and
zeros, plot them on the s-
plane, determine the type of
response, and then calculate
the system's time response if
the excitation is a unit step.
