Determine workdone on jet and catapult plus#
So we have, 1100 times 10 to the 3 newtons, on the one side, plus 65 times 10 to the 3 newtons, on the other side divide that total by 2, we multiply it by 85 meters for the base of the trapezoid, and we get 5.0 times 10 to the 7 joules is the work done by the catapult. And the area of the trapezoid is the height of one side plus the height of the other side divided by 2 and then multiplied by the base.
The work done by the catapult is the area of this trapezoid that's the area shaded in yellow here, everything underneath that curve. a)What is the mass of the jet b) If the jet is in contact with the catapult for 2s, what is the power output of the catapult asked by Clayton. The work done catapult during the launch is 7.6 x 10 to the 7th J. And the force exerted by the gas is in the same direction as the displacement so that work is positive. a atapult launcher on an aircraft carrier accelerates a jet from rest to 72m/s. And so the gas exerts a force of 130 kilonewtons, which is times 10 to the 3 newtons, times 85 meters which is 1.1 times 10 to the 7 joules of work done. Save those foam to go containers and you might find some that have flat. Back to the relative position concept, an aircraft can move at a fixed airspeed (speed relative to air/wind), but relative to the ground, it will travel faster with the wind and.
And it looks like, the plane takes off over a distance of 85 meters here, according to this force displacement diagram for the catapult. Total weight was a little heavier than using craft glue but the plane flew fine. Once the aircraft no longer has catapult assist, it relies on its own power from the jet engines pushing against air (like in the prior video talking about rockets). Answer (a) 1.1 × 10 7 J (b) 5 × 10 7 J View Answer Discussion You must be signed in to discuss. All of these changes made the carrier capable of carrying new aircraft that weigh. Determine the work done on the jet: ( a) by the gases expelled by its engines during launch of the jet and ( b) by the catapult during launch of the jet. The work done by the gas is the force exerted by the gas times the displacement. Once the force from the catapult is added to the thrust of the jet. The Electromagnetic Aircraft Launch System (EMALS) is a type of aircraft launching system developed by General Atomics for the United States Navy.The system launches carrier-based aircraft by means of a catapult employing a linear induction motor rather than the conventional steam piston.EMALS was first installed on the lead ship of the Gerald R.
