2. Relevant equations

p = iv

i = dq/dt

w = intergral of p dt = intergral of vi dt

3. The attempt at a solution

I don't really understand how to do this problem. First of all, I know that the area under the graph between some time interval is equal to the charge.

So for the part A of the question, I got the following, but I dont even know if its correct.

a) @ 1s = 2C, @3s = -1C, @4.5s = 0C

I don't know how to do the rest.
