![a = 4.18 m/s^2](https://tex.z-dn.net/?f=a%20%3D%204.18%20m%2Fs%5E2)
Direction
Opposite to the velocity of aircraft
Explanation:
As we know that the initial speed of the aircraft when it land on the ground is
![v_i = 77 m/s](https://tex.z-dn.net/?f=v_i%20%3D%2077%20m%2Fs)
now the final speed of the aircraft when it covers 705 m on runway is given as
![v_f = 6.3 m/s](https://tex.z-dn.net/?f=v_f%20%3D%206.3%20m%2Fs)
so here we know that
![v_f^2 - v_i^2 = 2 a d](https://tex.z-dn.net/?f=v_f%5E2%20-%20v_i%5E2%20%3D%202%20a%20d)
so now we can say that
![6.3^2 - 77^2 = 2ad](https://tex.z-dn.net/?f=6.3%5E2%20-%2077%5E2%20%3D%202ad)
![6.3^2 - 77^2 = 2(a)(705)](https://tex.z-dn.net/?f=6.3%5E2%20-%2077%5E2%20%3D%202%28a%29%28705%29)
![a = -4.18 m/s^2](https://tex.z-dn.net/?f=a%20%3D%20-4.18%20m%2Fs%5E2)
There are a few different formulas for electrical power. They involve
different combinations of voltage, current, and resistance.
==> Power = (current)² x (resistance)
==> Power = (voltage)² / (resistance)
==> Power = (voltage) x (current) .
In this case right now, we know the voltage and current, so maybe
it's a good idea to use the formula that involves voltage and current.
Power = (voltage) x (current)
= (120 volts) x (2.3 Amperes)
= 276 watts .
