Homework Statement
You need to calculate the acceleration (m/s 2 ) of a jet fighter which is launched from
an aircraft-carrier by catapult, given the jet’s required takeoff speed (km/hr) and the
distance available on deck to reach that speed (metres) as the catapult accelerates the
jet from rest to takeoff. Assume constant acceleration. You are also to calculate the
time (secs) for the jet to be accelerated to takeoff speed. You are also required to
report the acceleration in terms of its g-force where g = 9.80665m/s 2 .
The analysis part of this lab is based around 2 simultaneous equations, with unknowns
for acceleration and time given velocity and distance. Solve these equations so that
you can calculate both acceleration and time in terms of distance and velocity. The
easiest way to do this is to solve the first equation for a (acceleration) and then to
substitute that expression into the second equation and then solve it for t (time).

Homework Equations
Relevant formulae are (simple Newtonian motion with initial velocity of 0):
v = at
s = ½at 2
where v = velocity, a = acceleration, t = time, s = distance.
The Attempt at a Solution
Hello
I don't understand the question, could someone please explain it to me?
I know the input or given data is velocity and distance
but how to solve everything? Thank you!
