On an aircraft carrier, a jet can be catapulted from 0 to 250 km/h in 2.05 s If the average force exerted by the catapult is 9.40×10^5 N , what is the mass of the jet?

The mass of the jet is 26,225

Explanation: Convert 250km to m =250,000

1 hour = 3600

Velocity = 69.4 m/s

a= change in v/change in t

69.4/2 = 34.7

9.10×105 / 34.7 = 26,225 KG

Yw and pls mark me as brainiest

mass = 27750 kg

Explanation:

acceleration: (change in velocity)÷(time)

acceleration = (final velocity - initial velocity) ÷ time taken

Given that:

Final velocity is 250 km/h and initial is 0 km/h and time is 2.05s

acceleration = [(250 - 0) ÷ 0.0005694444]

acceleration = 439024.4 km/h²

conversion to m/s² :

acceleration = 439024.4 m/s²

Force = mass(kg) * acceleration(m/s²)

we know that force is  9.40×10^5 N

9.40×10^5 = mass(kg) *   33.875 (m/s²)

mass =  9.40×10^5 ÷  33.875

mass = 27750 kg

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
