A steam catapult launches a jet aircraft from the aircraft carrier John C. Stennis, giving it a speed of 190 mi/h in 2.70 s.
a.) Find the average acceleration of the plane.
b.) Assuming the acceleration is constant, find the distance the plane moves.
avg a = 190mph/2.70s = 70.37mi/(hr•s)
Convert that to the units of choice (probably ft/s) and then
s = 1/2 a*2.7^2
