Transcription: This example looks like any of the other examples we've been doing, but there is a twist. We're given the initial velocity, zero miles per hour. We're also given the final velocity, 60 miles per hour north. We also know the time, 6.1 seconds. So you might think we just plug into the equation. The final velocity is 60 miles per hour. The initial velocity, zero miles per hour. The time, 6.1 seconds. So the acceleration is 60 miles per hour minus zero over 6.1 seconds, right? Wrong. We have a terrible problem in our equation. Our time units don't agree. At the top of the fraction, our time units ...
