A jet plane is cruising at 300 m/s when suddenly the pilot turns the engines up to full throttle. After traveling 3.1 km , the jet is moving with a speed of 400 m/s. Part A What is the jet's acceleration, assuming it to be a constant acceleration? Express your answer to two significant figures and include the appropriate units. a a = nothing nothing Request Answer

Respuesta :

Answer:

11 m/s²

Explanation:

u = Initial velocity of the jet = 300 m/s

v = Final velocity of the jet = 400 m/s

s = Displacement of the jet = 3.1 km = 3100 m

a = Acceleration of the jet

Equation of motion

[tex]v^2-u^2=2as\\\Rightarrow a=\frac{v^2-u^2}{2s}\\\Rightarrow a=\frac{400^2-300^2}{2\times 3100}\\\Rightarrow s=11.29=11\ m/s^2[/tex]

Acceleration of the jet is 11 m/s²

The acceleration of the jet is 11.29 m/s2.

How do you calculate the acceleration?

Given that the initial velocity of the jet is 300 m/s, the final velocity of the jet is 400 m/s. The distance traveled by jet is 3.1 km.

The acceleration of the jet is calculated as given below.

[tex]v^2 = u^2 + 2as[/tex]

Where v is the final velocity, u is the initial velocity, a is the acceleration and s is the distance traveled by jet.

[tex]400^2 = 300^2 + 2\times a\times 3.1 \times 1000[/tex]

[tex]a = 11.29 \;\rm m/s^2[/tex]

Hence we can conclude that the acceleration of the jet is 11.29 m/s2.
