A car starts from rest and reaches a speed of 25m/s in 4 seconds. What is the acceleration? Also, Calculate the distance the object traveled,

Can y’all help me with this one

Answer in explanation.

Explanation:

Using Equation

where v is the final velocity

u is initial velocity

a is acceleration

t is time taken

given u = 0, v = 25, t = 4,

Now, using equation

where v and u remains the same, a = 6.25 and s is the distance,

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.

it was given as a lesson and guide for prayer.
