Greek engineers had the unenviable task of moving large columns from the quarries to the city. one engineer, chersiphron, tried several different techniques to do this. one method was to cut pivot holes into the ends of the stone and then use oxen to pull the column. the 4-ft diameter column weighs 13200 lbs, and the team of oxen generates a constant pull force of 1500 lbs on the center of the cylinder g. knowing that the column starts from rest and rolls without slipping, determine the velocity of its center g after it has moved 5 ft and the minimum static coefficient of friction that will keep it from slipping.

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.
