Acceleration of a plane and the g-force

AI Thread Summary
The discussion focuses on calculating the force produced by a steam catapult during the launch of an F/A-18 jet, which accelerates from 0 to 250 km/hr over 76 meters. Key calculations include determining the acceleration, the kinetic energy (Ek) of the jet as it departs the deck, and the resulting "g-force" experienced by the pilot. The kinetic energy can be calculated using the formula Ek = 1/2 mv^2, where m is the mass of the jet. Participants suggest starting with the kinetic energy to relate it to the work done during the launch. Understanding these calculations is essential for grasping the physics behind aircraft launch systems.

Acceleration of a plane and the "g-force"

Homework Statement


Steam catapults are used to launch aircraft. During the launch of a F/A-18 jet (mass: 16,770 kg) the catapult accelerates from 0 to 250 km/hr within 76m of deck length. Calculate the force produced by the catapult, the acceleration of the plane, and the Ek of the plane as it leaves the deck. What is the "g-force" on the pilot?

Homework Equations


Ek = 1/2 mv^2

The Attempt at a Solution


i have no clue how to even start this problem, sorry :l

It is probably easier to work backwards for this problem. Can you start by working out the kinetic energy of the plane as it leaves the deck as well as its initial kinetic energy? How is this change in kinetic energy related to the work done?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
