Amechanic jacks up the front of a car to an angle of 8.0° with the horizontal in order to change the front tires. the car is 3.05 m long and has a mass of 1130 kg. gravitational force acts at the center of mass, which is located 1.12 m from the front end. the rear wheels are 0.40 m from the back end. calculate the magnitude of the torque exerted by the jack.

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.
