Description	Let us imagine that we are building an airport that has to support planes that require takeoff speeds of at least 33 meters per second. Since we are dealing with a plane that is accelerating with a constant value, we must use the four equations derived in the previous lecture to solve the problem. (a) Someone proposes that the runway should be 120 meters long and it is our goal to prove or disprove the statement. In order to figure out whether or not the plane will be able to take off on this runway, we need to determine what the velocity of the plane is when it reaches the 120 meter mark. We have to use the equation that will allow us to solve for the final velocity. With a little bit of calculation, we see that the runway is not long enough for the plane to take off because the velocity reached by the plane is less than what is required for takeoff. (b) Now, given the fact that a 120 meter long runway is not long enough for our plane to take off, we need to figure out what the minimum length of our runway should be. In order to figure out the distance, we need to figure out how long it takes the plane to reach a velocity of 33 meters per second given the fact that it accelerates at a constant rate of 3.0 meters per second second. Since every second, our plane increases its velocity by 3 meters per second it will take the plane 11 seconds to reach the required velocity for takeoff. We use this information and solve for the distance.
