Homework Help: Physics

Posted by Lindsay on Wednesday, October 3, 2007 at 1:25pm.

A Cessna airplane can accelerate from rest to a ground speed of 78 knots in 29.8 s. What is the average acceleration of this airplane?

I figured out that 78 knots is equal to 89.76 miles, 144.45 km, or 144,450 m. And I think the equation might be average=delta V over delta t. But I'm not sure if this is right...help!
