A steam catapult launches a jet aircraft (from rest) from the aircraft carrier John C. Stennis, giving it a speed of 160 mi/h in 2.40 s.
Find the average acceleration of the plane.
Assuming that the acceleration is constant, find the distance the plane moves.
160 miles per hour = 234.67 ft/s = 71.53 m/s is the velocity change during launch
I trust you know how to do the conversions.
Divide either of the last two numbers by the time interval, 2.40 s.
That will give you the acceleration in ft/s^2 or m/s^2 units, respectively.
