Answer:
Mass of the jet, m = 28511.5 kg
Explanation:
It is given that,
Initial velocity if the jet, u = 0
Final velocity of the jet, v = 140 mi/h = 62.58 m/s
Time, t = 1.95 s
Average force, [tex]F=9.15\times 10^5\ N[/tex]
We need to find the mass of the jet. According to second law of motion as :
F = m × a
[tex]F=m\times \dfrac{v-u}{t}[/tex]
[tex]m=\dfrac{F.t}{v-u}[/tex]
[tex]m=\dfrac{9.15\times 10^5\ N\times 1.95\ s}{62.58\ m/s-0}[/tex]
[tex]m=28511.5\ kg[/tex]
So, the mass of the jet is 28511.5 kg. Hence, this is the required solution.
