Find the power delivered to an element at t = 3 ms if the current entering its positive terminal is I = 5 cos 60πt and the voltage is a)V = 3I b)V = 3 dI/dt

A current i(t) = 7+ 4sin 2t passes through a capacitor at time t. The capacitor is uncharged at time t= 0. Find the charge q(t) at all time t.
