Un avión, cuando toca pista, acciona todos los sistemas de frenado, que le generan una desaceleración de 5 m/s2. Si necesita 100 metros de recorrido para frenar por completo, ¿con qué
velocidad venía el avión antes de tocar pista y frenar? ¿Cuánto tiempo duró el proceso de frenado?

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
