A fish swimming in horizental plane has velocity vi=(4j+j)m/s at a point in the ocean when aposition relative with acertain rock is Ri=(10i-4j)m After The Fish Swimms With Constant Acceleration For 20s it isvelocity is Uf=(20i-5j) m/s. A) find The Accelaration Of The Fish
2) If The Fish Maintains This Constant Acceleration Where Is It At T=25s

the force required to move the cart is divided by three or 33.33 n.

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.
