My car is currently broken. I was going around a roundabout when I braked, my car slowed to 40 MPH. I tried to accelerate but my car wouldn’t go any faster. I slowed down for the second roundabout, then my car wouldn’t go past 20 MPH. After that the car stopped moving. Now I have to jump the battery to start the car.

It sounds like the battery is shorted out and needs replacement or the alternator is not working here are two guides to help you fix the problem.
