Aman weighing 680n and a woman weighing 500n have the same momentum. what is the ratio of the man's kinetic energy km to that of the woman kw?

a cardinal (richmondena cardinalis) of mass 3.60

Explanation:

given,

weight of the man = 680 N

weight of the woman = 500 N

mass of man =

  M_m = 69.4 Kg

mass of woman

=

M_w = 51 Kg

ratio of man's kinetic energy Km to that of the woman Kw

momentum is same

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.
