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?

Answer:

mass = 27750 kg

Step-by-step 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

  • change 2.05s to hrs. that is 0.0005694444 hrs

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
