if you take off a velocity of an airplane on a runaway is 300 km/hr with an acceleration of 1 m/s^2 what is the take off time of the airplane

if you take off a velocity of an airplane on a runaway is 300 kmhr with an acceleration of 1 ms2 what is the take off time of the airplane class=

Respuesta :

Given:

The take-off velocity of the airplane, v=300 km/hr

The acceleration of the plane, a=1 m/s²

To find:

The take-off time.

Explanation:

The airplane starts from the rest and accelerates up to the take-off velocity. Thus the initial velocity of the airplane is u=0 m/s

The final velocity in m/s is

[tex]\begin{gathered} v=300\times\frac{1000}{3600} \\ =83.33\text{ m/s} \end{gathered}[/tex]

From the equation of motion,

[tex]v=u+at[/tex]

Where t is the take-off time of the plane.

On substituting the known values,
