In order for a plane to take off, it must be traveling at 160mph and requires a runway of
.7 mile. What is the constant acceleration required for the plane to take off. I am doing something wrong. I integrated velocity to get position, as well as integrating acceleration to get velocity. I am not getting an answer that makes sense.

Whoa, why do you want to integrate?

1. Work out the average speed of the plane (remeber it's constant acceleration)
2. Work out how long it takes the plane to travel to the end of the runway
3. Work out the acceleration!
