Question

A steam catapult launches a jet aircraft (from rest) from the aircraft carrier John C. Stennis, giving it a speed of 200 mi/h in 3.00 s.
(a) Find the average acceleration of the plane.

Answer 1

\[v_{final}=v _{initial}+at\]\[200mph = 0 + a * 3.00s\]
Now just solve for a to get \[66.67 mph ^{2}\]

Answer 2

v = u + at
a = v-u/t
a = 200 - 0/3
a = 66.7 mph^2
