## Homework Statement

1.On an aircraft carrier, an F18 Super Hornet can be catapulted from 0 to a take-off speed of 248 km/hr. The loaded mass of this jet in fighter configuration is 21,320 kg. The length of the angled section of the flight deck on the US Nimitz class carriers is 237 m. What minimum force must be applied to the jet?

2.A train is traveling up a 3.73-degree incline at a speed of 3.25 m/s when the last car breaks free. How far does the last car travel before its speed momentarily reaches zero?

## Homework Equations

These weren't given to me, just the ones I've tried using:

F=ma

d=Vo2 + 1/2at2

Vf=Vo + at

d = (Vf2-Vo2)/2a

Vox = Vocos(theta)

Voy = Vosin(theta)

## The Attempt at a Solution

I have made several attempts at these questions, but I am not very good at physics so I honestly do not know if they were even close, thus why I didn't bother posting them. Any help, even just a starting point or concept explanation, is greatly appreciated.
