What is the momentum of a tiger that has a mass of 81 kg and runs with a velocity of 5.4 m/s to the east

Given :

Mass of tiger , m = 81 kg .

Velocity of tiger , v = 5.4 m/s .

To Find :

The momentum of tiger .

Solution :

We know , momentum of a body is given by the product of its mass and velocity .

Now , putting value of m and v in above equation , we get :

Therefore , the momentum of tiger is 437.4 kg m/s .

Hence , this is the required solution .

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.
