Answer:
Force = 80422.4 N
Explanation:
Given that,
Initial speed, u = 0 m/s
Final speed, v = 1900 km/h = 527.78 m/s ( 1 km/h = [tex]\frac{1}{3.6}[/tex] m/s)
Time taken, t = 2.1 s
So, Applying equation of motion as:
[tex]v=u+at\\\Rightarrow a=\frac{v-u}{t}\\\Rightarrow a=\frac{527.78-0}{2.1}\ m/s^2\\\Rightarrow a=251.32\ m/s^2[/tex]
According to the Newton's second law of motion:-
[tex]Force=Mass\times Acceleration[/tex]
Mass = 320 kg
So,
[tex]Force=320\times 251.32\ kgm/s^2[/tex]
Force = 80422.4 N
