How do the displacement, velocity, and acceleration of a runner change as he races from the starting line toward the finish line along a straight path?

oh- i see now, okey so if the positioning if velocity the that will increases the speed..but it says an runner.. so if you think of yourself going down an hill with this velocity you will probably will fall, because of the angle.

i hope this helped.

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.
