(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The initial voltage on the 0.5 microF capacitor shown in the figure is -20 V. the capacitor current has the waveform shown in the figure. https://i.imgur.com/P8jwI7s.jpg?1

How much energy is stored in the capacitor at t = 870 micro seconds.

2. Relevant equations

v(t) = 1/c * integral from t to t0 i dtao + v(t0) EDIT: "integral from t to t0" is a definite integral with t on the top and t0 on the bottom

w(t) = 1/2cv^2

3. The attempt at a solution

got v(t) = 50*e^-2000t + 30

after plugging into w(t) tested the following answers:
