A driver sees a car braking sharply in front of him. The driver takes 0.5 s to react to the stimulus and then brakes.
shows the velocity-time graph for the motion of the vehicle
from seeing the stimulus to stopping. Calculate the stopping
distance of the vehicle.

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.
