Aprojectile falls beneath the straight-line path it would follow if there were no gravity. how many meters does it fall below this line if it has been traveling for 1 s?

Explanation:

Suppose v is the initial velocity and is the angle of inclination

distance traveled in vertical direction in t=1 s

When gravity is present

where

here initial velocity is v\sin \theta [/tex] so

In absence of gravity

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.
