A horizontal rope is attached from a truck to a 1368-kg car. As the truck tows the car on a horizontal straight road, the rope will break if the tension is greater than 2738 N. Ignoring friction, what is the maximum possible acceleration of the truck if the rope does not break?

0.11 m/s and 0.28 m/s should be correct

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.
