A circuit consists of an ideal ac generator, a capacitor, and an ideal inductor, all connected in series. The charge on the capa
citor is given by Q = (16 µC) cos (ωt + π/4) where ω = 1290 rad/s. (a) Find the current in the circuit as a function of time

4)
Explanation:
1)
We can use the following equation:
Here, the initial velocity in the y-direction is zero, the final y position is zero and the initial y position is 25 m.
2)
The equation of the motion in the x-direction is:
3)
The velocity in the y-direction of the stone will be:
Now, the velocity in the x-direction is 15 m/s then the velocity will be:
4)
The angle of this velocity is:
Then α=55.92° negative from the x-direction.
I hope it helps you!
