Wile E. Coyote is at the top of a 235m high cliff. He has an anvil that he intends to
drop on the Road Runner who is running on a road with a velocity of 2.2- m/s. If the
road is directly below the cliff, and the coyote sees the Road runner, 175m from the
coyote's position when should the coyote drop the anvil in order to
squash Road Runner?

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.

this could be newton#'s law of cooling. the cooling curve is exponential

because growing process had stoped after 4-5 year
