Una avioneta para aplicar agroquímicos debe alcanzar una velocidad de 28 m/s para poder despegar. Si el motor provee una aceleración efectiva de despegue de 1.5 m/s2, determine: La longitud efectiva mínima que debe tener la pista para que la avioneta pueda despegar, si en la carrera de despegue recorre la pista partiendo del reposo, desde un extremo de la misma.

x = 261.3 m

Explanation:

In this problem we can use kinematic relations in one dimension

        v² = v₀² + 2 ax

the speed is v = 25 m / s, as part of the rest v₀ = 0 and they indicate that the acceleration is a = 1.5 m / s²

       x = v² / 2 a

calculate

       x = 28²/2 1.5

       x = 261.3 m

this distance in no wind that helps or hinders the take off

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
