A bulldozer drags a 252 kg log along the rough horizontal ground. The cable attached to the log applies a 525 N force at an angle of 30.0° above the ground. The coefficient of kinetic friction between the log and the ground is 0.150. Assume the direction of motion is + x and upward is + y . 1.) What is the normal force acting on the log?
2.) What kinetic friction force is acting on the log? Include the proper sign.
3.) What is the acceleration of the log?

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.
