Voltage through a capacitor

. can someone help?http://www.kpsec.freeuk.com/capacit.......
I'm having a bit of a stupid moment right now:

The current through a 0.2 microfarad capacitor is a rectangular pulse with amplitude 2mA and a duration of 4ms. Find the capacitor voltage at the end of the pulse when the voltage at the beginning is -2V.

IDK why I can't figure this out... can someone help?
