Transcription: I'm going to start with the second half of this example because it's more illustrative than the first half. In the second half of this example, we're asked to calculate the acceleration of a biker. We're given the initial velocity. He's biking down at 18 feet per second east. We also know his final velocity even though it's not explicitly stated. The problem says that the biker comes to a halt. That means the final velocity is zero. We're also given the time, 1.8 seconds. So we have all the data that we need to calculate acceleration. Okay, we go to our equation. Acceleration equals final velo ...
