Hello, I've attached the problem here! Can someone help me out please?

Problem #1: Determine the stress response 0(1) for the Maxwell model in response to a strain function (where a is a constant): (t)=at, t 20 For E = 100 kPa and n = 500 kPa-s, plot the stress responses for a = 0.01 3'1 and a = 0.02 3'1 from 0 to 10 s. Then plot the stress vs. strain plots for each value of a
