Acceleration and Braking

• You can accelerate to a particular velocity, but at any velocity you'll eventually go over L.
• Of course, the faster your velocity, the faster you'll get there.
• The key is to put on the brakes at the right time.
• That is you want velocity to be 0 right when you get to L.
• If your velocity is V, what you need to do is to accelerate in the opposite direction.
• Accelerating in the opposite direction is braking.
• You can time slice it, so that it comes to a rest on roughly L.
• Calculus can get you to exactly L theoretically, but this assumes things like no friction, which isn't true even in space.
