g A thin uniform cylindrical turntable of radius 2.4 m and mass 32 kg rotates in a horizontal plane with an initial angular speed of 10 rad/s. The turntable bearing is frictionless. A clump of clay of mass 13 kg is dropped onto the turntable and sticks at a point 1.7 m from the point of rotation. Find the angular speed of the clay and turntable. Answer in units of rad/s.

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.

the answer is 12 as i may remember
